Abstract:
This article describes the analysis and design of the excitation schemes of the plasmonic angular ring resonator-based band-pass filters using a metal-insulator-metal (MIM) waveguide. The excitation schemes of the plasmonic angular ring resonator-based band-pass filters have been analyzed in terms of their physical length by using commercially available electromagnetic full-wave simulation software (CST microwave studio). The excitation schemes of the plasmonic angular ring resonator-based band-pass filter using a MIM waveguide have been realized at the optical O (1260–1360 nm) and U (1625–1675 nm) bands, respectively, as it has dual-band characteristics. The excitation schemes of the plasmonic angular ring resonators have been designed and simulated to determine the variation in transmission and reflection coefficients. The magnetic field distribution of the proposed filters was observed. The ring resonators require low power and had a compact size, which was further used for the development of photonic integrated circuits (PICs). The applications of these resonators are further extended and they are used in the development of antennas, branch line couplers, directional couplers and diplexers.

Abstract:
We studied the metal-insulator-metal square ring resonator design incorporated with nano-dots that serve to squeeze the surface plasmon wave in the cavity of the ring. The E-field enhances at the boundaries of the nano-dots providing a strong interaction of light with the surrounding medium. As a result, the sensitivity of the resonator is highly enhanced compared to the standard ring resonator design. The best sensitivity of 907 nm/RIU is obtained by placing seven nano-dots of radius 4 nm in all four sides of the ring with a period (ᴧ)= 3r. The proposed design will find applications in biomedical science as highly refractive index sensors. Full Text: PDF References:Z. Han, S. I. Bozhevolnyi.

Abstract:
AbstractPhotonic and plasmonic refractive index sensors are able to detect increasingly smaller refractive index changes and concentrations of clinically relevant substances. They typically exploit optical resonances and aim to maximise the field overlap with the analyte in order to achieve high sensitivity. Correspondingly, they operate on the basis of maximizing the bulk sensitivity, which favours spatially extended modes. We note that this strategy, counter-intuitively, is not necessarily suitable for detecting biomolecules and one should focus on the surface sensitivity instead. Here, we show that by confining light tightly in metal-insulator-metal (MIM) nanoresonators, the surface sensitivity is significantly increased despite a clear decrease in bulk sensitivity. In particular, we experimentally show the operation of third order MIM resonators which support both extended surface plasmon polariton (SPP) modes and localized MIM modes. We are able to demonstrate that the MIM mode has a sensitivity of 55 nm/RIU to a 10 nm layer, which is approximately twice as high as that of the SPP mode. Overall, our work emphasizes the importance of the surface sensitivity over the more commonly used bulk sensitivity and it shows a novel approach for improving it. These insights are highly relevant for the design of next generation optical biosensors.

Abstract:
For processing of desired information, the present-day electronic equipment is rapidly approaching their ultimate speed and bandwidth constraints, which is an ever more serious problem that prevents their persistent use in applications. It is believed that a promising solution is to fabricate electronic and photonic elements on a single chip. This mechanism provides a larger bandwidth that is used to construct new hybrid electronic photonic devices. In this paper the numerical analysis and design of metal-insulator-metal plasmonic directional coupler are presented. In dual optical bands, this directional coupler design needed the concept of the step impedance resonators (SIRs). Without reducing the subsystems, the enhanced architectures that pertain to filtering as well as multiplexing devices are necessary for conclusion of these kinds of specifications. Photonic-integrated circuits (PICs) have effectively improved their work by present design directional coupler, and it can be mixed with the conventional silicon PICs.

Abstract:
Le contrôle des ondes électromagnétiques joue un rôle fondamental dans les technologies photoniques actuelles. De nos jours, on assiste à une demande croissante de composants agiles capable d'absorber efficacement les ondes électromagnétiques dans divers gamme de fréquences. Habituellement, ces absorbeurs s'appuient sur les résonances plasmoniques qui apparaissent dans les métaux nobles dans la gamme visible. Cependant, l'extension des propriétés plasmoniques aux spectres infrarouge et THz nécessite des matériaux adéquats ayant un comportement métallique à ces fréquences. Dans ce travail, nous étudions numériquement et expérimentalement les structures métal-isolant-métal (MIM) réalisées à partir de semi-conducteur hautement dopé Si: InAsSb qui a un comportement métallique dans la gamme infrarouge. Dans la deuxième partie, nous avons amélioré l'efficacité des résonateurs MIM en utilisant des métamatériaux hyperboliques qui miniaturisent les résonateurs. Dans la dernière partie, nous proposons un design universel ultra-mince qui permet de dépasser les contraintes associées au choix des matériaux et permettant la réalisation d'un absorbeur fonctionnant sur une gamme spectrale allant de l'infrarouge aux micro-onde
The control of light absorbance plays a fundamental role in today's photonic technologies. And the urge to design and develop flexible structures that can absorb electromagnetic waves is very growing these days. Usually, these absorbers relies on plasmonic resonances that arise in noble metals in the visible range. However, the extension of the plasmonic properties to the infrared and THz spectra requires adequate materials that have a metallic behavior at these frequencies. In this work, we study numerically and experimentally the metal-insulator-metal (MIM) structures realized from highly doped semiconductor Si:InAsSb that has a metallic behavior in the infrared range. In the second, part we improved the efficiency of the MIM resonators by using hyperbolic metamaterials that also miniaturize the resonators. In the last part, we propose an ultra-thin universal design that overcomes the material barrier so that the total absorption can be achieved for different spectral ranges without changing the material

Abstract:
A low-temperature (<300°C) method to fabricate electrostatically actuated microelectromechanical (MEM) clamped-clamped beam resonators has been developed. It utilizes an amorphous silicon carbide (SiC) structural layer and a thin polyimide spacer. The resonator beam is constructed by DC sputtering a tri-layer composite of low-stress SiC and aluminum over the thin polyimide sacrificial layer, and is then released using a microwave O 2 plasma etch. Deposition parameters have been optimized to yield low-stress films (<50MPa), in order to minimize the chance of stress-induced buckling or fracture in both the SiC and aluminum. Characterization of the deposited SiC was performed using several different techniques including scanning electron microscopy, EDX and XRD.
Several different clamped-clamped beam resonator designs were successfully fabricated and tested using a custom built vacuum system, with measured frequencies ranging from 5MHz to 25MHz. A novel thermal tuning method is also demonstrated, using integrated heaters directly on the resonant structure to exploit the temperature dependence of the Young's modulus and thermally induced stresses.

Microfabricated transducers have enabled new approaches for detection of biomolecules and cells. Integration of electronics with these tools simplify systems and provide platforms for robust use outside of the laboratory setting. Suspended microchannel resonators (SMRs) are sensitive microfluidic platforms used to precisely measure the buoyant mass of single cells and monolayers of protein in fluid environments. Conventionally, micro cantilever deflection is measured by the optical-lever technique, wherein a laser beam is reflected off the cantilever onto a position sensitive photodiode. This thesis introduces microchannel resonators with electronic readout, eliminating the use of external optical components for resolving the sensor's resonant frequency. Piezo resistors have been fabricated on SMRs through ion implantation integrated with the existing SMR fabrication process. We fabricated two designs: one with a cantilever length of 210 pm and resonant frequency of -347 kHz, and the other with a cantilever length of 406 pm and resonant frequency of ~92 kHz. The work here builds upon knowledge of signal transduction from static and dynamic cantilever based sensors because the piezo resistors are implemented on vacuum encapsulated devices containing fluid. Electronic readout is shown to resolve the microchannel resonance frequency with an Allan variance of 5 x 10-18 (210 pm) and 2 x 1017 (406 pm) using a 100ms gate time, corresponding to a mass resolution of 0.1 and 0.4 fg respectively. This mass resolution calculated from piezoresistive readout frequency stability, is approximately 3X better than optical readout for the 210 pm device and 1.3X for the 406 pm device using the same gate time. Resolution is expected to improve with further optimization of the system. To demonstrate the readout, histograms of the buoyant masses of a mixture of size standard polystyrene beads (with nominal diameters 1.6, 1.8, and 2.0 pm) and budding yeast cells were made.

Abstract:
The ever-decreasing size of electronic circuits leads to the challenge of an antenna becoming one of the biggest components in most portable wireless electronic devices. lIenee recent miniaturization techniques such as dielectric resonator antenna (DRA) technology employing compact non-conducting dielectric materials as radiating elements continue to be explored. This thesis seeks the application of DRAs in radio frequency identification (RFID) tags to tackle the problem of frequency detuning and loss of matching faced by most tag antennas when mounted on metallic backgrounds. It then investigates antenna polarization diversity for addressing the challenge of limited space available on small mobile devices for multiple-input multiple-output (MIMO) communication systems by employing single compact narrowband dual- and tri-port regular DRAs and proposed dual-port broadband (4 - 7 GHz) bowtie DRAs and their two-element arrays on representative personal digital assistant (PDA) blocks.

This work extends the use of our high performance (less than 0.05 dB insertion loss, greater than 30 dB isolation) high-Tc superconductor MEM switch to a switched-based coplanar waveguide "T"-resonator structure. The most significant advantages here are its low mass and volume. Competitive technologies require actuators on the order of a few milligrams to a few tens of grams or more and volumes of the order of tens of cm3. The integrated MEM devices present the designer with an alternative of a mass of a few micrograms and a volume of less than 5x 10-6 cm3 at the same performance levels. The design of the switch was optimized using Sonnet simulations.

Ce travail de thèse porte sur la conception et la réalisation de méta-structures pour l’amelioration des performances de détecteurs dans les gammes spectrales du moyen infrarouge et du térahertz (THz). Ces méta-structures sont des matrices de résonateurs métalliques qui actent aussi comme antennes, permettant une meilleure collection des photons et un plus fort confinement du champ électrique. Dans ce manuscrit, j’examine les résultats expérimentaux concernant deux photo-detecteurs infrarouges à puits quantiques (QWIP) résonants à une longueur d'onde de 55.5 µm (5.4 THz) et de 8.6 µm, implémentés dans des réseaux d’antennes patch. La responsivité, la détectivité et les performances thermiques des dispositifs en microcavité sont systématiquement comparées au même détecteur fabriqué en géométrie standard ‘mesa’, pour lequel le rayonnement infrarouge est couplé par le substrat. La cohérence du modèle est évaluée en comparant le gain photoconducteur de chaque structure QWIP. Dans le moyen infrarouge, le fonctionnement à température ambiante avec une source de radiation thermique est démontré pour la première fois. De plus, en exploitant la courte durée de vie des porteurs dans la zone de QWIP, une détection hétérodyne à température ambiante a été démontrée jusqu’aux fréquences de quelques GHz, limitée uniquement par la fréquence de coupure du circuit externe. Dans la dernière partie de ce manuscrit, plusieurs perspectives sont discutées concernant des structures de détecteurs quantiques couplés à la géométrie de résonateurs patch et des architectures inspirées des métamateriaux, avec la perspective d’améliorer davantage les performances des photodétécteurs
The present thesis manuscript is about the conception and the realisation of metastructures for the improvement of detector performances in the mid-infrared and terahertz (THz) spectral ranges. These meta-structures are arrays of metal resonators that also act as antennas, allowing a better collection of photons and a stronger confinement of the electric field. In this manuscript, I examine the experimental results regarding a 55.5 µm (5.4 THz) and a 8.6 µm quantum well infrared photodetectors (QWIP), implemented into patch-antennae arrays. The responsivity, the specific detectivity and the thermal performances of the antenna-coupled devices are systematically compared to the same detector processed in standard substrate-coupled ‘mesa’ geometry. In the mid-infrared, the room temperature operation using a thermal radiation source is reported for the first time. Moreover, exploiting the short carrier lifetime in semiconductor quantum wells, a room temperature heterodyne detection is demonstrated, at frequencies up to few GHz, limited only by the cut-off frequency of the external circuit. In the last part of this work, several perspectives are discussed, regarding alternative quantum detector structures coupled to the patch resonators geometry and innovative circuit-like plasmonic architectures, envisioning orders of magnitude improvement in photodetector performances

Abstract:
Existing unified numerical electromagnetic methods are often unable to analyze electrically large structures due to the amount of memory and processing power required, necessitating approximate analyses with limited applicability. In this research a hybrid modeling methodology is adopted to solve these complex problems more efficiently than unified numerical methods and more accurately than analytical methods. Electromagnetic modeling problems are divided into two or more levels of scale. Each level analyzes a specific level of detail and only promotes the required information to the next level. The method is demonstrated by successful application to three important problems: (1) remote sensing of snow, (2) modeling an optical Bragg resonator, and (3) modeling the MIMO wireless channel. First, complex snow media is analyzed with a hybrid FDTD/radiative transfer model. FDTD is used to compute phase matrices and extinction coefficients required for radiative transfer. Comparison with exact analytical methods proves the validity of the FDTD method for modest domain sizes ([5λ^3]) and number of Monte Carlo realizations (32). The method is used to illustrate a penetrating sphere model, which is not possible with existing analysis techniques. Backscatter from the resulting model is about 3 times higher than that of existing dense-medium theories, underlying the importance of exact characterization of the media. Second, a hybrid FD/FDTD/S-parameter analysis is developed to model a large (10^4 section) optical Bragg resonator: a simple FD method computes propagation constants and field profiles, FDTD analysis provides reflection and transmission coefficients for the single section, and S-parameter analysis combines the sections to obtain the complete device response. A detailed study on error suggests that the method provides better than 2% accuracy in reflection and transmission response. Third, a hybrid electromagnetic/SVA model is developed to study the indoor MIMO wireless channel. A MIMO measurement platform is discussed for simultaneous probing of up to 16 transmit and receive antennas, which was required to assess the validity of later modeling. FDTD or MOM antenna analysis coupled with the SVA model gives capacity predictions which match measured data. The model is used to explore the impact of antenna spacing, directivity, and polarization on channel capacity. Closely spaced antennas lead to an approximate halving of receive power. Directivity effectively doubles receive power for aligned transmit and receive. Dual polarization increases system capacity anywhere from 10% to 70%, depending on the spacing of elements and the amount of multipath richness. This analysis of MIMO systems underlines the need for models that describe both multipath richness and average receive power.

Abstract:
L'information est devenue le bien le plus précieux au monde. Ce mouvement vers la nouvelle ère de l'information a été propulsé par la capacité à transmettre l'information plus rapidement, à la vitesse de la lumière. Il est donc apparu nécessaire de mener des recherches plus poussées pour contrôler plus efficacement les supports d'information. Avec les progrès réalisés dans ce secteur, la plupart des technologies actuelles de contrôle de la lumière se heurtent à certains obstacles tels que la taille et la consommation d'énergie et sont conçues pour être passives ou sont limitées technologiquement pour être moins actives (technologie Si-back). Même si rien ne voyage plus vite que la lumière, la vitesse réelle à laquelle les informations peuvent être transportées par la lumière est la vitesse à laquelle nous pouvons la moduler ou la contrôler. Ma tâche dans cette thèse visait à étudier le potentiel du VO2, un matériau à changement de phase, pour la nano-photonique, avec un accent particulier sur la façon de contourner les inconvénients du matériau et de concevoir et démontrer des dispositifs intégrés efficaces pour une manipulation efficace de la lumière à la fois dans les télécommunications et le spectre visible. En outre, nous démontrons expérimentalement que les résonances multipolaires supportées par les nanocristaux de VO2 (NC) peuvent être réglées et commutées dynamiquement en exploitant la propriété de changement de phase du VO2. Et ainsi atteindre l'objectif d'adaptation de la propriété intrinsèque basée sur le formalisme de Mie en réduisant les dimensions des structures de VO2 comparables à la longueur d'onde de fonctionnement, créant un champ d'application pour un métamatériau accordable défini par l'utilisateur
Information has become the most valuable commodity in the world. This drive to the new information age has been propelled by the ability to transmit information faster, at the speed of light. This erupted the need for finer researches on controlling the information carriers more efficiently. With the advancement in this sector, majority of the current technology for controlling the light, face certain roadblocks like size, power consumption and are built to be passive or are restrained technologically to be less active (Si- backed technology). Even though nothing travels faster than light, the real speed at which information can be carried by light is the speed at which we can modulate or control it. My task in this thesis aimed at investigating the potential of VO2, a phase change material, for nano-photonics, with a specific emphasis on how to circumvent the drawbacks of the material and to design and demonstrate efficient integrated devices for efficient manipulation of light both in telecommunication and visible spectrum. In addition to that we experimentally demonstrate the multipolar resonances supported by VO2 nanocrystals (NCs) can be dynamically tuned and switched leveraging phase change property of VO2. And thus achieving the target tailoring of intrinsic property based on Mie formalism by reducing the dimensions of VO2 structures comparable to the wavelength of operation, creating a scope for user defined tunable metamaterial

Abstract:
Mitt-Infrarot-Technologie (mid-IR) ist ein äußerst leistungsfähiges Werkzeug für die Anwendung in der Molekülspektroskopie, da die Schwingungsmoden vieler Moleküle in diesem Wellenlängenbereich liegen. Der Quantenkaskadenlaser mit externem Resonator (EC-QCL) kann alle Bereiche dieses Spektrums abdecken. Das Hauptanliegen dieser Arbeit ist die Verbesserung der Leistung des EC-QCL im Hinblick auf die Breite des Wellenlängen-Durchstimmbereichs und die Laserleistung. Theoretische Untersuchungen bestätigen zunächst, dass der QCL die Schlüsselrolle bei EC-Systemen einnimmt: Die Effizienz des EC wird bestimmt durch die Effizienz des QCL und die Güte der Antireflex-Schicht (ARC) der Laserfacette. Die Breite des Durchstimmbereichs wird bestimmt durch das Gain-Spektrum des QCL. Im Rahmen dieser Arbeit wurden die QCL in unserer Gruppe hergestellt und vom QCL-Wachstum selbst bis hin zur Facettenbeschichtung optimiert. Eine der größten Herausforderungen in der Herstellung des EC-Systems ist die Reduktion des Reflexionsvermögens innerhalb der Facetten des Laserchips. Dafür haben wir ein neues ARC-Konzept entwickelt und auf dem beschichteten Substrat demonstriert, dass innerhalb des gesamten, sehr breiten Wellenlängenbereichs von 7–12 μm die Reflexion auf unter 1% reduziert wird. Das Beschichtungsmodell wurde außerdem auf „broad-gain“-QCL-Facetten angewendet, wodurch die Reflexion auf 0,75% über den gesamten Emissions-Wellenlängenbereich reduziert werden konnte. Ein weiterer Schwerpunkt dieser Arbeit ist die Entwicklung und Konstruktion von EC-Lasersystemen. Es wurden zwei kompakte Laser vom Littrow-Typ entwickelt, die von 920 cm-1 bis 1190 cm-1 durchstimmbar sind und die eine Pulsleitung von 0.45 W erreichen. Außerdem wurde eine neue optische Konfiguration des EC-Systems vorgeschlagen um eine höhere Ausgangsleistung zu erzielen. Dieser „Intra-cavity Out-coupling Laser“ erreicht eine Pulsleistung von 1 W und den gleichen Emissionbereich wie die beiden Littrow-Laser.
Mid-infrared (mid-IR) technology is a very powerful tool for molecular spectroscopy since vibration modes of many molecules lie in this wavelength range. The External-Cavity Quantum Cascade Laser (EC-QCL) can cover any part of this spectral range. The main goal of this study is to improve EC-QCL performance in terms of wavelength tunability and laser power. The theoretical study about Quantum Cascade Laser (QCL) and EC systems has confirmed that the QCL plays the core role of EC-QCL systems; the power efficiency of an EC system is determined by the combination of the power efficiency of QCL and AR-coating of the laser facet. The width of the tuning range is determined by the gain spectrum of QCL. During this work, QCLs have been fabricated in our group and the optimization of these factors were carried out with various approaches, from QCL growth to facet coatings. One of the major challenges in making EC systems is to reduce the intra-facet reflectivity of the laser chip, and we first proposed a new anti-reflection (AR) coating concept and demonstrated its performance for the first time to the community, achieving good reduction of reflection of the AR-coated substrate over 7-12 μm range, keeping below R < 1% reflection over the entire spectrum. The coating model was applied on broad-gain QCL facets, and the reflection was reduced to 0.75% over the entire emission wavelength range. Furthermore, this work focused on the development and engineering of laser systems, and two compact Littrow-type lasers and an EC system with a new optical configuration have been developed, achieving good performances; tunable from 920 cm-1 to 1190 cm-1 and 0.45 W pulse power. The new type of laser, an Intra-cavity out-coupling EC laser, was also proposed to enhance the power output and achieved over 1 W pulse power with keeping the same tuning range as the Littrow-type.
中赤外分光の技術は非常に有用である。これはとりわけ多くの分子振動モードがこの波長帯域に存在しているためである。可変長レーザーである外部共振器量子カスケードレーザー(External cavity quantum cascade laser, EC-QCL)は、これらスペクトル領域を網羅することが可能で、したがって、EC-QCLは産業スケールを含めた、標準的な光源として非常に潜在的である。商品化のフェーズをさらに推し進めるため、このレーザー性能におけるボトムアップの技術が求められてる。 多くの中赤外光のアプリケーションには広帯域の光源が求められている。この研究はおもにそうした性能を最大化することを背景としている。具体的な目的としては、波長の変調性および光源の強度の向上である。これらの目的に取り組むため、我々はいくつかの段階にステージ化して研究を進めてきた。まず初めに、QCLおよびEC-QCLの基本的な特性の追求から始めた。QCLおよびEC-QCLの物理機構の理論的な考察を行い、これらからEC-QCL形態における要素の最適条件もしくは要請を求めた。QCL素子が、その主要な部位であり、EC系におけるほとんどの性能特性である量子効率、変調領域幅、増幅器の光学損失を決定する。 さまざまなアプローチによりこれら緒特性の最適化が行われた。 この研究のなかで、我々グループ内でシステムの心臓となるQCL素子の全製造プロセス(結晶成長から素子コーティングに至るまで)をおこなった。これら製造手順および性能特性の詳細もまた本論文に記す。 ECレーザーにおける要請特性の中で特に困難な課題として、レーザー素子の内部断面(intra-facet)の反射率の低減があげられる。これに応じるものとして、我々は新たな反射防止膜のコンセプトで、特に中赤外光領域に有益なものを提案した。この実現のために、様々な誘電体物質の光学特性を調べ、中赤外光の応用に最適なものを選択し、実際のコーティングに応用した。ここで提案されたモデル``quasi-Lockhart'' (疑ロックハート)のコーティングは、実験によりその高い性能が実証された。波長7–12 μmの領域をカバーし、かつその全領域内で反射率を1%以下に抑えることができた。またこのコーティングは広帯域ゲインのチップにも施され、その反射率を全体域をカバーしながら、0.75%まで低減させた。この成果はEC-QCLだけでなく、一般の中赤外光の光学コーティングにおいても大いに有用であろう。 さらに、我々は本研究の中でレーザーシステムの構築にも取り組んだ。この研究のなかで、二台のLittrow型レーザーと、新たな光学系をもつECレーザーを構築し、その高性能性を実証した。Littrow型では920 cm-1-1190 cm-1の帯域とパルス強0.45 Wを達成。新たなレーザーシステムであるIntra-cavity out-coupling系は従来の系にくらべ高出力することを目的とされ、その帯域を維持しながら、パルス強1~Wの出力を達成した。またこれら新たなシステムを用いて、またプロジェクトバートナーとの食道癌の細胞イメージングも試験、およびグループにおいてアンモニアの吸光度測定を実施した。

Abstract:
This work considers geopolitical and postcolonial themes in a range of writings by Jorge Luis Borges, analysing the development of a postcolonial sensibility in works such as ‘Mythical Founding of Buenos Aires’, ‘Tlön, Uqbar, Orbis Tertius’, ‘Theme of the Traitor and the Hero’, and ‘Brodie’s Report’. It examines Borges’s treatment of national and regional identity and of East–West relations in several essays and poems, contained, for example, in Other Inquisitions, The Self and the Other, and Seven Nights. The theoretical concepts of ‘coloniality’ and ‘Occidentalism’ shed new light on several works by Borges, who acquires a sharper political profile than previously acknowledged. The book pays special attention to Oriental subjects in Borges’s works of the 1970s and 1980s, where their treatment is bound up with a critique of Occidental values and assumptions. Classified by some commentators as a precursor of postcolonialism, Borges emerges as a prototype of the postcolonial intellectual exemplified by James Joyce, Aimé Césaire, and Edward Said. From a regional perspective, his repertoire of geopolitical and historical concerns resonates with those of Leopoldo Zea, Enrique Dussel, Eduardo Galeano, and Joaquín Torres, amongst others, who illustrate different strands and kinds of Latin American postcolonialism(s) of the mid- to late twentieth century. At the same time, essential differences in respect of political and artistic temperament mark Borges out as a postcolonial intellectual and creative writer who is unquestionably sui generis.

Abstract:
E-government refers to a set of public administration and governance goals and practices involving information and communication technologies (ICTs). It utilizes such technologies to serve public agencies’ external audiences and constituents. However, the scope of that service is the subject of much debate and, consequently, no consensual definition of e-government had been formulated. The prehistory of e-government resonates with assumptions from the “new public management” (NPM), which proposed a restructuring of governmental agencies by adopting a market-based approach to ensure cost efficiencies in the public sector. Coined in the mid-1990s, the notion of e-government as equivalent to better government, economic growth, human development, and the knowledge society in general was quickly and uncritically accepted by practitioners and scholars alike. As scholars from different disciplines, including politics communication and sociology, paid increasing attention to the intersections of structural factors, hardware, and culture in the adoption and use of ICTs, research on e-government began to show some diversification. By the twenty-first century, the number of e-government websites from local and national administrations has grown sufficiently to allow some generalizations based on empirical observation. Meanwhile critical and comprehensive approaches to e-government frequently adopt a critical stance to denounce oversimplifications, determinisms, and omissions in the formulation of e-governance projects, as well as in the evaluation, adoption, and assessment of e-government effectiveness. Beyond the particularities of each emerging technology, reflection on the intersections between ICTs and government is moving away from an exclusive focus on hardware and functionality, to consider broader questions on governance.

Abstract:
This chapter proposes the use of asynchronously coupled-resonator junctions (ACJ) in the design of a multi-input multi-output (MIMO) filtering network and a masthead combiner (MHC). By employing the resonator junctions, miniaturised circuits are achieved without using any transmission-line-based impedance matching circuits. The main challenge in the designs is the control and implementation of the external couplings at the common ports of this all-resonator-based MIMO filtering network and MHC. Both devices are four ports-based with the MIMO filtering network operating at 1.8, 2.1, and 2.6 GHz, while the MHC operates at the two channels of 1.8 and 2.1 GHz. The demonstrated designs achieved fractional bandwidths of 1.764 GHz to 1.836 GHz, 2.058 GHz to 2.142 GHz, and 2.548 GHz to 2.652 GHz, respectively. Good agreements have been achieved between the measurements of the prototype devices and the simulations.

Abstract:
Adaptive-passive devices such as adaptive Helmholtz Resonators (HR) and tunable vibration absorbers have been shown to be suitable for controlling both narrowband disturbances and lightly damped structural/acoustic modes driven by broadband disturbances. In order to track changes in the disturbance or changes in the modes, the natural frequency of the absorber, ωn, is tuned to match the observed signals. This is achieved by altering some physical parameter of the control device such as the stiffness of a vibration absorber or the neck cross-sectional area of a Helmholtz resonator. In order to automatically adjust these devices, control systems and tuning algorithms have been developed, most of which involve a digital controller. However, this paper looks specifically at the development of a simple analog controller used to drive a DC motor in order to tune a mechanical device. A two sensor dot product method is employed where one sensor is placed inside of the control device, such as a Helmholtz Resonator, and the other on/in the system under control, such as in a room. The outputs from the two sensors are multiplied together and subsequently low passed in order to extract a low frequency “DC” voltage which acts as an error signal. The error signal is related to the relative phase of the two sensor signals and determines the direction in which the device should be tuned. When the two signals are 90° apart, the system is tuned (i.e. the inner product produces zero DC level). If the drive frequency ω is different than the tuned frequency, then the system is mis-tuned. The relationship between the mis-tuning, ωn-ω, and the error is not linear, but for small perturbations a linear approximation can be used to investigate the stability and performance of the system. The gradient of the function is shown to be largest when the mis-tuning error is zero and is inversely proportional to the damping level in the control device. Once stability of the system has been ensured the ability of the system to track changes in drive frequency is investigated experimentally. The control system is demonstrated using an adaptive Helmholtz resonator which has a variable cross-sectional neck via an iris diaphragm. The iris is controlled using a small DC motor; two microphones (one mounted internally and one externally) are used to supply the driving signal to the circuit.
