Abstract:

Abstract. Near-field far-field transformations (NFFFTs) are commonly performed for time-harmonic fields. Considering arbitrary in-situ measurement scenarios with given transmission signals, time-varying aspects of modulated signals have to be taken into consideration. We investigate and characterize two methods for the measurement of modulated fields, which work with a time-domain representation of the radiated fields and, at the same time, allow to employ the standard time-harmonic NFFFT. One method is based on the fact that the modulation signal can be assumed to be constant in a short enough measurement interval under the condition that the modulation and carrier frequencies are several decades apart. The second method performs long-time measurements in order to obtain the complete frequency spectrum in every single measurement. Both methods are verified by the NFFFT of synthetic field data.

Abstract:

An effective one-dimensional model approach combining time-dependent pseudospectral method and Taylor expansion [Haoxue Qiao et al., Phys. Rev. A65, 063403 (2002)] is generalized to study a real hydrogen atom in an intense laser field. High-order harmonic generations are calculated in several cases of different laser field parameters. The ionization probability is also calculated. The influence of the strong magnetic field on harmonic generations is investigated. It is found that the plateau of high harmonics can be extended by the magnetic field and the cutoff order increases with the increase of the field intensity.

Abstract:

Wave propagation problems in unbounded domains require the handling of appropriate radiation conditions (Sommerfeld). Various absorbing boundary conditions are available for that purpose. In a discrete finite element context, local and global Dirichlet-to-Neumann (DtN) and infinite element methods have shown their efficiency for the scalar wave equation. The paper concentrates on the extension of an infinite element method to the elastodynamic vector wave equation. The extension is developed in the frequency domain for 2-D problems. The paper focuses on the development of a conjugated formulation using the Helmholtz decomposition theorem of smooth vector fields. The accuracy of the developed formulation is assessed through the study of benchmarks. The computed results are shown to be in good agreement with the analytical solution for a multi-pole field along a circular cavity and with the results produced by other numerical methods.

Abstract:

The vacuum, as described by Quantum Field Theory, is not as empty as classical physics once led us to believe. In fact, it is characterised by an infinite energy stored in the ground state of its constituent fields. This infinite energy has real, tangible effects on the macroscopic clusters of matter that make up our universe. Moreover, the configuration of these clusters of matter within the vacuum in turn influences the form of the vacuum itself and so forth. In this work, we shall consider the changes to the quantum vacuum brought about by the presence of time-dependent dielectrics. Such changes are thought to be responsible for phenomena such as the simple and dynamical Casimir effects and Quantum Friction. After introducing the physical and mathematical descriptions of the electromagnetic quantum vacuum, we will begin by discussing some of the basic quasi-static effects that stem directly from the existence of an electromagnetic ground state energy, known as the \textit{zero-point energy}. These effects include the famous Hawking radiation and Unruh effect amongst others. We will then use a scenario similar to that which exhibits Cherenkov radiation in order to de-mystify the 'negative frequency' modes of light that often occur due to a Doppler shift in the presence of media moving at a constant velocity by showing that they are an artefact of the approximation of the degrees of freedom of matter to a macroscopic permittivity function. Here, absorption and dissipation of electromagnetic energy will be ignored for simplicity. The dynamics of an oscillator placed within this moving medium will then be considered and we will show that when the motion exceeds the speed of light in the dielectric, the oscillator will begin to absorb energy from the medium. It will be shown that this is due to the reversal of the 'radiation damping' present for lower velocity of stationary cases. We will then consider how the infinite vacuum energy changes in the vicinity, but outside, of this medium moving with a constant velocity and show that the presence of matter removes certain symmetries present in empty space leading to transfers of energy between moving bodies mediated by the electromagnetic field. Following on from this, we will then extend our considerations by including the dissipation and dispersion of electromagnetic energy within magneto-dielectrics by using a canonically quantised model referred to as 'Macroscopic QED'. We will analyse the change to the vacuum state of the electromagnetic field brought about by the presence of media with an arbitrary time dependence. It will be shown that this leads to the creation of particles tantamount to exciting the degrees of freedom of both the medium and the electromagnetic field. We will also consider the effect these time-dependencies have on the two point functions of the field amplitudes using the example of the electric field. Finally, we will begin the application of the macroscopic QED model to the path integral methods of quantum field theory with the purpose of making use of the full range of perturbative techniques that this entails, leaving the remainder of this adaptation for future work.

Abstract:

This thesis describes methods for using spectral interferometry for the complete space-time characterisation of few-cycle near-infrared femtosecond pulses and extreme ultraviolet (XUV) attosecond pulses produced via high harmonic generation (HHG). Few-cycle pulses tend to exhibit one or more of the following: (1) an octave-spanning bandwidth, (2) a highly modulated spectrum and (3) space-time coupling. These characteristics, coupled with the desire to measure them in a single-shot (to characterise shot-to-shot fluctuations) and in real-time (for online optimisation and control) causes problems for conventional characterisation techniques. The first half of this thesis describes a method, based on a spatially encoded arrangement for spectral phase interferometry for direct electric-field reconstruction (SEA-SPIDER). SEA-SPIDER is demonstrated for sub-10fs pulses with a central wavelength near 800nm, a bandwidth over 350nm, and a pulse energy of several nano-Joules. In addition, the pulses exhibit a modulated spectrum and space-time coupling. The spatially-dependent temporal intensity of the pulse is reconstructed and compared to other techniques: interferometric frequency-resolved optical gating (IFROG) and spectral phase interferometry for direct electric field reconstruction (SPIDER). SEA-SPIDER will prove useful in both femtoscience, which requires accurate knowledge of the space-time character of few-cycle pulses, and in HHG, which requires the precise knowledge of the driving pulse for seeding into simulations and controlling the generation process itself. Pulses arising from HHG are known to exhibit significant space-time coupling. The second half of this thesis describes how spectral interferometry may be performed to obtain the complete space-time nature of these fields via the use of lateral shearing interferometry. Finally, it is shown, via numerical simulations, how to extend the SPIDER technique for temporal characterisation of XUV pulses from HHG by driving the process with two spectrally-sheared driving pulses. Different experimental configurations and their applicability to different laser systems are discussed. This method recovers the space-time nature of the harmonics in a single shot, thus reducing the stability constraint currently required for photoelectron based techniques and may serve as a complimentary method for studying interactions of XUV attosecond pulses with matter.

Abstract:

Broadband spectral content is required to support ultrashort pulses. However this broadband content is subject to dispersion and hence the pulse duration of corresponding ultrashort pulses may be stretched accordingly. I used a commercially-available adaptive ultrashort pulse shaper featuring multiphoton intrapulse interference phase scan technology to characterise and compensate for the dispersion of the optical system in situ and conducted experimental and theoretical studies in various inter-linked topics relating to the light-matter interaction. Firstly, I examined the role of broadband ultrashort pulses in novel light-matter interacting systems involving optically co-trapped particle systems in which inter-particle light scattering occurs between optically-bound particles. Secondly, I delivered dispersion-compensated broadband ultrashort pulses in a dispersive microscope system to investigate the role of pulse duration in a biological light-matter interaction involving laser-induced cell membrane permeabilisation through linear and nonlinear optical absorption. Finally, I examined some of the propagation characteristics of broadband ultrashort pulse propagation using a computer-controlled spatial light modulator. The propagation characteristics of ultrashort pulses is of paramount importance for defining the light-matter interaction in systems. The ability to control ultrashort pulse propagation by using adaptive dispersion compensation enables chirp-free ultrashort pulses to be used in experiments requiring the shortest possible pulses for a specified spectral bandwidth. Ultrashort pulsed beams may be configured to provide high peak intensities over long propagation lengths, for example, using novel beam shapes such as Bessel-type beams, which has applications in biological light-matter interactions including phototransfection based on laser-induced cell membrane permeabilisation. The need for precise positioning of the beam focus on the cell membrane becomes less strenuous by virtue of the spatial properties of the Bessel beam. Dispersion compensation can be used to control the temporal properties of ultrashort pulses thus permitting, for example, a high peak intensity to be maintained along the length of a Bessel beam, thereby reducing the pulse energy required to permeabilise the cell membrane and potentially reduce damage therein.

Abstract:

Im Bereich der industriellen Metallurgie und Kristallzüchtung treten bei zahlreichen Anwendungen, wo magnetische Wechselfelder zur induktiven Beeinflussung von leitfähigen Werkstoffen eingesetzt werden, auch Strömungen mit freier Oberfläche auf. Das Anwendungsspektrum reicht dabei vom einfachen Aufschmelzen eines Metalls in einem offenen Tiegel bis hin zur vollständigen Levitation. Auch der sogenannte RGS-Prozess, ein substratbasiertes Kristallisationsverfahren zur Herstellung siliziumbasierter Dünnschichtmaterialien, ist dafür ein Beispiel. Um bei solchen Prozessen die Interaktion von Magnetfeld und Strömung zu untersuchen, ist die numerische Simulationen ein wertvolles Hilfsmittel. Für beliebige dreidimensionale Probleme werden entsprechende Berechnungen bisher durch eine externe Kopplung kommerzieller Programme realisiert, die für Magnetfeld und Strömung jeweils unterschiedliche numerische Techniken nutzen. Diese Vorgehensweise ist jedoch im Allgemeinen mit unnötigem Rechenaufwand verbunden. In dieser Arbeit wird ein neu entwickelter Methodenapparat auf Basis der FVM vorgestellt, mit welchem sich diese Art von Berechnungen effizient durchführen lassen. Mit der Implementierung dieser Methoden in foam-extend, einer erweiterten Version der quelloffenen Software OpenFOAM, ist daraus ein leistungsfähiges Werkzeug in Form einer freien Simulationsplattform entstanden, welches sich durch einen modularen Aufbau leicht erweitern lässt. Mit dieser Plattform wurden in foam-extend auch erstmalig dreidimensionale Induktionsprozesse im Frequenzraum gelöst.

In this thesis, we measure the far-field second harmonic generation (SHG) in various-oriented BiFeO3 thin films by femtosecond laser pulses with 800 nm. From the symmetry of SHG pattern, we could analyze the relationship between the SHG and the polarization in BiFeO3. Moreover, the SHG in the BiFeO3-CoFe2O4 nanostructure samples can be measured by a home-made Scanning Near-field Optic Microscopy (SNOM). By comparing the results of SNOM and PFM, the mechanism of SHG in BiFeO3 thin films could be further revealed. Finally, the time-resolved SNOM has been performed here to study the ferroelectric domain in BiFeO3 thin films.

Abstract:

The finite element method is a powerful method for the approximate solution of boundary value problems governed by partial differential equations. A really first application to structural engineering problems, dating 1943, is attributed to R. Courant. Since then, there has been a lot of successful tentatives to apply the method to other fields. In particular, Silvester showed in 1969 that waveguide modes could be easily computed with the method. His work started a long path for finite elements in electromagnetics, with multiple assessments of the method with real-world problems and gradually improving the efficiency of the algorithms. Nowadays, finite elements in computational electromagnetics has become an invaluable part in radio frequency and microwave application designs, and many packages are widely available to perform these tasks. However, there remain a lot of problems to be solved. In this dissertation, we have inquired in two of these. The first, the efficient solution of large problems which may not be solvable on a single modern computer. Domain decomposition methods have been thus investigated, these allowing to solve smaller parts of a large problem and to achieve the whole solution upon proper interconnection. Two types of domain decomposition methods have been analyzed, leading to the construction of algorithms for solving large electromagnetic problems at a nearly linear complexity. The other, the accurate solution of electromagnetic problems in which some materials behave nonlinearly, that is their properties vary depending on the intensity of the fields they imbue. Almost all materials behave nonlinearly and their effect is just a matter of fields intensities and accuracy requirements. In many microwave applications, the nonlinear effects, necessary for information processing and control, are still limited to lumped devices for their highly developed models. Accurate modeling of bulk or films of nonlinear materials may open the way to a new variety of controllable materials in flexible, reconfigurable, electromagnetic devices. A finite element package has been implemented to perform several tests here documented.

Abstract:

High energy radiation is an important tool for many fields of research as it allows for the measurement of smaller structures and atomic interactions. The current best method of generating coherent and narrow bandwidth synchrotron radiation is with a free electron laser. It requires very high charge density, to start the amplification process and concurrently leads to its high level of coherency, and high energies (GeV to obtain keV photons). The stringent parameters on the electron bunch are met by linear accelerators. These are typically kilometre long straight structures that operate from tens to 100 Hz repetition rate. A novel design was proposed by the INFN Milan research group called MariX [1]. Here a LINAC is used in combination with a com- pression arc. This reduces the size of the facility, because the electron bunch can be accelerated twice by the same LINAC. As the electrons pass through dipoles in the compression arc the fields emanating from the particles in the bunch can cause deterioration to it. These fields, consisting out of the relativistic Coulomb-and radiation field, travel with the speeds of light, and thus originate from a point in the past. For this reason the behaviour of these retarded fields is investigated from first principles and developed into a 3D algorithm for calculating the forces within a bunch. An in depth overview is given on how the constituent fields behave over a large range of electron energies. Proportionality relations are given that determine which one is dominant. To reach unprecedented high energy photons is through the scattering of intense lasers with electron bunches; (inverse) Thomson or Compton scattering. Photon energies of keV can be reached with tens of MeV electrons, and MeV photons with GeV electrons. High repetition rate collisions are possible with cavity based laser systems. Currently the power in-side the cavity is several hundreds of kW with an intensity at the focus up to 1014−15 [W/cm2]. With these high powers the cavities can become degenerate, i.e. higher order transverse modes are excited, either by imperfections of the mirrors or deformations caused by heat dissipation. A short study provides insights to the observability of these modes in the Thomson spectrum. The general method for Thomson scattering is to have a (quasi) monochromatic laser pulse collide with an electron bunch with a very small energy spread. The latter usually leads to a reduction of the number of charges, and therefore the flux of scattered photons. The frequency of the scattered radiation is linearly dependent on that of the laser’s, and therefore the energy spread of the electrons could be compensated by including a frequency modulation. The highest intensity lasers obtained are by chirped pulse amplification and thus readily available. Two schemes have been investigated: longitudinal and transverse chirp. Both can reach the limit in bandwidth and number of photons scattered of the mono-energetic and mono-chromatic case. For ultra shorted pulses the carrier envelope phase becomes an important variable. Thomson scattering can be used to measure For intensities where non-linear effects dominate, because the scattered radiation contains the information of the laser pulse.. A model of its signature in the Thomson spectrum has been developed: it shifts the peaks of higher harmonics that overlap. This shift is also correlated to the emission direction of harmonics. A detailed analysis is given how to measure it experimentally.

Abstract:

Echocardiography has become the most requested imaging modalities. It is the first line imaging in the diagnostic work-up and monitoring of most cardiac diseases. Echocardiography is harmless and combines low-cost high technology with easy accessibility. The advent of the new modalities such as harmonic imaging, tissue Doppler imaging, speckle tracking, real time 3-dimensional imaging, ad contrast cavity enhancement have also contributed to expand the role of echocardiography. It provides rapid quantitative information about cardiac structure and function, valvular motion, vascular system and haemodynamics at bedside. This imaging technique is considered an extension of the physical examination. Proper technical skills and knowledge are required for the optimal application of echocardiography. Disease-focused and succinct, the present handbook covers the information needed to perform and interpret echocardiogramsaccurately, including how to set up the echomachine to optimize an examination and how to perform echocardiographic disease assessment, and the clinical indicators, procedures, and contraindications. Sections include assessment of the left ventricular systolic dysfunction and diastolic function, discussion on ischaemic heart disease, heart valve disease, cardiomyopathies, pericardial disease, congenital heart disease, and many other aspects of echocardiology. Many talented people have contributed to the present handbook, which represents the pocket echocardiography book flagship of the European Association of Cardiovascular Imaging. This book is intended principally as a clinical guide to the broad field of echocardiography at a glance.

Abstract:

Film music represents one of the few remaining underexplored frontiers for the field of music theory. Discovering its inner workings from a theoretical perspective is imperative if we wish to understand its tremendous effects on the ears (and eyes) of the twentieth and twenty-first centuries. Hollywood Harmony applies for the first time the tools of contemporary music theory and analysis to this corpus in a thorough and systematic way. In order to help readers appreciate how film music works, this study enlists a number critical apparatuses, ranging from abstract theoretical description to psychological models and sensitive close reading. It argues that matters of musical structure in film are matters of musical meaning, and pitch relations are inherently expressive, always somehow collaborating with visuals and narrative. One harmonic idiom, pantriadic chromaticism, plays an especially important role in the “Hollywood Sound,” and much of this study is dedicated to understanding its aesthetic and expressive content—of which the elicitation of a feeling of wonder is paramount. For better understanding of this tonal practice on a rigorous level, the transformational tools of neo-Riemannian theory are introduced and applied in an accessible and novel way. Neo-Riemannian theory emphasizes musical change and gesture over fixed objects or structures, and by recognizing the innate spatiality of musical experience in extended-tonal settings, it serves as an excellent lens through which to inspect film music. The works of a diverse assortment of composers are examined, with particular attention given to recent “New Hollywood” scoring practices.

Abstract:

AbstractA physical stochastic parameterization is adopted in this work to account for the effects of the unresolved small-scale on the large-scale flow dynamics. This random model is based on a stochastic transport principle, which ensures a strong energy conservation. The dynamic mode decomposition (DMD) is performed on high-resolution data to learn a basis of the unresolved velocity field, on which the stochastic transport velocity is expressed. Time-harmonic property of DMD modes allows us to perform a clean separation between time-differentiable and time-decorrelated components. Such random scheme is assessed on a quasi-geostrophic (QG) model.

Abstract:

AbstractIn this chapter, the attention is paid to two fields which are linked with family lifestyle. The first one concerns socioeconomic situations in a family and shows that the economic side of family functioning is actually very essential these days. The importance of family economic situation is affirmed also in the results of our international survey. We asked what was the main family income, experience with unemployment and whether our respondents had possibility to save some money. Furthermore, we were interested in expenditure items and in evaluation of an overall standard of living by respondents. The Germans and then Czechs evaluated it as the best, the worst was found in families in Latvia. The second part monitors life satisfaction as a subjective feeling of well-being and is understood as a part of quality of life. To the question “How do you imagine a satisfied family?”, the most frequent response was—harmonic coexistence without conflicts, well-being, good health of all family members and material security. For the question “What do you lack to your satisfaction?” respondents stated—financial security and lack of free time for the family. However, there were specific differences among individual surveyed countries.

Abstract:

This chapter considers some well-known results on the solvability and layer potentials for static and time-harmonic elasticity equations. It first reviews commonly used function spaces before introducing equations of linear elasticity and decomposing the displacement field into the sum of an irrotational (curl-free) and a solenoidal (divergence-free) field using the Helmholtz decomposition theorem. It then discusses the radiation condition for the time-harmonic elastic waves, which is used to select the physical solution to exterior problems. It also describes the layer potentials associated with the operators of static and time-harmonic elasticity, along with their mapping properties, and proves decomposition formulas for the displacement fields. Finally, it derives the Helmholtz–Kirchhoff identities, analyzes Neumann and Dirichlet functions, and states a generalization of Meyer's theorem concerning the regularity of solutions to the equations of linear elasticity.
