Abstract:
Abstract. We study the wave-related (AC) and static (DC) parallel Poynting vector (Poynting energy flux) as a function of altitude in auroral field lines using Polar EFI and MFE data. The study is statistical and contains 5 years of data in the altitude range 5000–30000 km. We verify the low altitude part of the results by comparison with earlier Astrid-2 EMMA Poynting vector statistics at 1000 km altitude. The EMMA data are also used to statistically compensate the Polar results for the missing zonal electric field component. We compare the Poynting vector with previous statistical DMSP satellite data concerning the electron precipitation power. We find that the AC Poynting vector (Alfvén-wave related Poynting vector) is statistically not sufficient to power auroral electron precipitation, although it may, for Kp>2, power 25–50% of it. The statistical AC Poynting vector also has a stepwise transition at R=4 RE, so that its amplitude increases with increasing altitude. We suggest that this corresponds to Alfvén waves being in Landau resonance with electrons, so that wave-induced electron acceleration takes place at this altitude range, which was earlier named the Alfvén Resonosphere (ARS). The DC Poynting vector is ~3 times larger than electron precipitation and corresponds mainly to ionospheric Joule heating. In the morning sector (02:00–06:00 MLT) we find that the DC Poynting vector has a nontrivial altitude profile such that it decreases by a factor of ~2 when moving upward from 3 to 4 RE radial distance. In other nightside MLT sectors the altitude profile is more uniform. The morning sector nontrivial altitude profile may be due to divergence of the perpendicular Poynting vector field at R=3–4 RE.

Abstract:
Recently, there has been increased interest in the shaping of light fields with an inverse energy flux to guide optically trapped nano- and microparticles towards a radiation source. To generate inverse energy flux, non-uniformly polarized laser beams, especially higher-order cylindrical vector beams, are widely used. Here, we demonstrate the use of conventional and so-called generalized spiral phase plates for the formation of light fields with an inverse energy flux when they are illuminated with linearly polarized radiation. We present an analytical and numerical study of the longitudinal and transverse components of the Poynting vector. The conditions for maximizing the negative value of the real part of the longitudinal component of the Poynting vector are obtained.

Abstract:
In this paper, we have investigated the focusing of a second-order cylindrical vector beam by using a high numerical aperture (NA) lens limited by a ring aperture using the Richards-Wolf formulae. It was shown that the range of negative on-axis projections of the Poynting vector could be increased by increasing the depth of focus through the use of a ring aperture. It was shown that when focusing light with a lens with NA = 0.95, the use of a ring aperture limiting the entrance pupil angle to 0.9 of maximum, allows the depth of the region of negative on-axis Poynting vector projections to be four times increased, with the region width remaining almost unchanged and varying from 0.357 to 0.352 of the incident wavelength. Notably, the magnitude of the reverse energy flow was found to be larger than the direct one by a factor of 2.5.

Abstract:
Efforts to suggest a classical model for the hydrogen atom are discouraged by a conclusion, based on the principles of electrodynamics, that an accelerating charged particle necessarily radiates. In this paper, we re-examine the steps leading to this conclusion. We start with the relativistic expressions for energy and momentum of a particle and establish the relationship between special relativity and electrodynamics. The standard field expression and its relativistic transformations are then studied for a point charge source, represented by a delta function. In conventional Poynting’s theorem analysis, the rate of change of work done on a system of charges is written as addition of two terms, rate of change of stored energy, and surface integral of Poynting vector. For a delta function source, the first two terms of this equation are either non-integrable or difficult to evaluate. Only the third surface integration term can be evaluated, which is said to give radiation by the point charge. Thus, the statement that an accelerated charge radiates is a conclusion based on this Poynting vector analysis. We examine it and realize that this statement, namely, that a point charge radiates continuously just because it is accelerating, does not have adequate theoretical justification.

Abstract:
This paper analizes the power emitted by charges accelerated on general trajectories. The electric and magnetic field radiated are calculated in detail through the retarded potentials, and the non-relativistic, quasistatic and radiation regimes are treated. The radiated power is obtained through the calculation of the Poynting vector, and the two cases of linear and circular accelerators are analyzed. After this, the distribution in frequencies of this radiation is studied for a moving charge and a moving magnetic moment, and the intensity distribution in angles and frequencies is generalized to the case of a continuous set of charges in motion.

Com a abertura legal do setor elétrico brasileiro na década de 90 para investimentos privados, em especial com a implantação sistemática de leilões para definição dos concessionários de transmissão, diversos estudos foram efetuados com o objetivo de viabilizar projetos de linha de transmissão de modo a concorrem nesses leilões. Grandes transmissoras, como Furnas, Chesf e Eletronorte promoveram pesquisas em consórcio com empresas construtoras de linhas e fabricante de ferragens e isoladores, com o objetivo de desenvolverem projetos com baixa relação Reais/MW transmitido. Neste cenário, muitos projetos de linhas de potência natural elevada foram idealizados e implantados, e como fruto desses projetos, publicações foram realizadas descrevendo os resultados obtidos. Todavia, apesar da quantidade, qualidade e riqueza das informações publicadas, a descrição do processo de otimização dos parâmetros elétricos da linha, em especial da impedância característica, não receberam destaque, sendo muita das vezes suprimida nos artigos. Neste sentido, este trabalho propõe a investigação de um método inovador de otimização da capacidade de transmissão de linhas de potência natural elevada, através da análise indireta dos efeitos da variação do posicionamento dos cabos condutores no feixe sobre a impedância característica da linha, por meio de uma abordagem original que utiliza basicamente o vetor de Poynting como função objetivo do Método de Otimização por Enxame de Partículas, sendo os campos elétricos e magnéticos necessários para definição do vetor de Poynting calculados por meio do Método dos Elementos de Contorno. O método foi validado utilizando como exemplos a otimização das configurações de feixes da linha de 500 kV Interligação Norte/SUL III – Trecho 2 e Linha de 500 kV Presidente Dutra / Teresina / Sobral / Fortaleza. Foram encontrados ganhos na capacidade de transmissão de 7% e 22% respectivamente devido à redução da impedância característica calculada após a otimização através da rotina Line Constants do programa ATP/EMTP, e comparando-a com os valores originais.
With the legal opening for private investments in the Brazilian energy sector in the 90's, in particular the systematic implementation of auctions for defining power transmission concessions, several studies were made with the aim of developing transmission line projects in order to compete in these auctions. Major transmission companies such as Furnas, Eletronorte and CHESF promoted consortium research with line builders and hardware and insulators manufacturers, in order to develop projects with low cost/MW transmitted. In this scenario, many projects of high surge-impedance loading lines were developed and implemented, and as a result of these projects, publications were made describing the results. However, despite the quantity, quality and resourcefulness of published information, the descriptions of the optimization process of electrical line parameters, especially regarding characteristic impedance, were not given prominence, being often suppressed from the articles. Thus, this study proposes the investigation of a method for optimizing the transmission capacity of high surge-impedance loading lines, varying the power cables in the bundle, indirectly reducing its characteristic impedance through an original approach that uses basically the Poynting's vector as objective function of the Particle Swarm Optimization method.The electric and magnetic fields needed for defining the Poynting vector were calculated using the Boundary Element Method. The method was validated through the optimization of bundle configuration, using as a model the characteristics of the 500 kV line North / South Interconnection III - Segment 2 and the 500 kV line Presidente Dutra / Teresina / Sobral / Fortaleza. It was found transmission capacity gains of 7% and 22% respectively, by reducing the characteristic impedance, which was calculated after the optimization using the EMTP/ATP Line Constants Program, comparing it with the original values.

Abstract:
The main objective of this thesis is to study and investigate the production of massive vector bosons (W+ and W−). This a priori mentioned production is not sensitive to hot nuclear matter effects because of the weak coupling nature of these vector bosons. Thus, in heavy ion collisions they provide a good reference for the medium-induced effects on other probes. The production mechanism of these vector bosons is highly isospin dependent and thus they are affected by the initial state effects. Initial state effects include isospin, Fermi motion, EMC effect, shadowing and nuclear absorption. Hence their production in lead-lead (Pb-Pb) and proton-lead (p-Pb) collisions can be used to test some of these initial state effects. In this thesis only two of these initial state effects will be considered namely, isospin and shadowing (referring to shadowing and anti-shadowing). Eke, these vector bosons can be used to provide a non-arbitrary reference to the probes affected by the medium. Traditionally, in heavy ion collisions, hard processes are expected to scale with the number of binary collision thus a precise study of these vector bosons can be used to test the factorisation assumed in models used to determine centrality. This unique property of electroweak (W) bosons makes them essential probes to study the possible inherent bias in centrality determination. In proton-proton (pp) collisions, their production can be used to obtain information on quark parton distribution functions (PDF). The data used in the analysis was collected by A Large Ion Collider Experiment (ALICE) at the Large Hadron Collider (LHC). The ALICE detector is designed to study ultrarelativistic heavy-ion collisions, in which a hot and dense, strongly-interacting medium is created. The production of W bosons is studied in p-Pb, p-p and Pb-Pb collisions at 5.023, 8 and 5.023 TeV centre-of-mass energies, respectively. The forward muon spectrometer with the pseudorapidity acceptance −4.0 < ŋ < −2.5 is used. W bosons are studied via the inclusive single muon differential pT spectrum.

Abstract:
In the last 15 years, power dissipation and energy consumption have become crucial design concerns for almost all computer systems. Technology feature size scaling leads to higher power density and therefore to complex and costly cooling. While power dissipation is critical for high-performance systems such as data centers due to large power usage, for mobile systems battery life is a primary concern. In the low-end mobile processor market, power, energy and area budgets are significantly lower than in the server/desktop/laptop/high-end mobile markets. The ultimate goal in low-end systems is also to increase performance, but only if area/energy budget is not compromised. Vector architectures have been traditionally applied to the supercomputing domain with many successful incarnations. The energy efficiency and high performance of vector processors, as well as their applicability in other emerging domains, encourage pursuing further research on vector architectures. However adding support for them using conventional design incurs area and power overheads that would not be acceptable for low-end mobile processors and also there is a lack of appropriate tools to perform this research. In this thesis, we propose an integrated vector-scalar design for the low-power ARM architecture that mostly reuses scalar hardware to support the execution of vector instructions. The key element of the design is our proposed block-based model of execution that groups vector computational instructions together to execute them in a coordinated manner. We complement this with an advanced integrated design which features three energy-performance efficient ideas: (1) chaining from the memory hierarchy, (2) direct result forwarding and (3) memory shape instructions. This thesis also presents two tools for measuring and analyzing an application suitability for vector microarchitectures. The first tool is VALib, a library that enables hand-crafted vectorization of applications and its main purpose is to collect data for detailed instruction level characterization and to generate input traces for the second tool. The second tool is SimpleVector, a fast trace-driven simulator that is used to estimate the execution time of a vectorized application on a candidate vector microarchitecture. The thesis also evaluates characteristics of Knights Corner processor with simple in-order SIMD cores. Acquired knowledge is applied in the integrated design.
En los últimos 15 años, la potencia disipada y el consumo de energía se han convertido en elementos cruciales del diseño de la práctica totalidad de sistemas de computación. El escalado del tamaño de los transistores conlleva densidades de potencia más altas y, en consecuencia, sistemas de refrigeración más complejos y costosos. Mientras que la potencia disipada es crítica para sistemas de alto rendimiento, como por ejemplo centros de datos, debido a su uso de gran potencia, para sistemas móviles la duración de la batería es la preocupación principal. Para el mercado de procesadores móviles de prestaciones más modestas, los límites permitidos para la potencia, energía y área del chip son significativamente más bajas que para los servidores, ordenadores de sobremesa, portátiles o móviles de gama alta. El objetivo final en sistemas de gama baja es igualmente el de incrementar el rendimiento, pero sólo si el "presupuesto" para energía o área no se ve comprometido. Tradicionalmente, las arquitecturas vectoriales han sido usadas en el ámbito de la supercomputación, con diversas implementaciones exitosas. La eficiencia energética y el alto rendimiento de los procesadores vectoriales, así como que se puedan aplicar a ámbitos emergentes, motivan a continuar la investigación en arquitecturas vectoriales. No obstante, añadir soporte paravectores basado en diseños convencionales conlleva incrementos de potencia y área que no son aceptables para procesadores móviles de gama baja. Además, no existen herramientas apropiadas para realizar esta investigación. En esta tesis, proponemos un diseño integrado vectorial-escalar para arquitecturas ARM de bajo consumo, que principalmente reutiliza el hardware escalar ya presente en el procesador para implementar el soporte de ejecución de instrucciones vectoriales. El elemento clave del diseño es nuestro modelo de ejecución por bloques propuesto en la tesis, que agrupa instrucciones de cómputo vectorial para ejecutarlas de manera coordinada. Complementamos esto con un diseño integrado avanzado que implementa tres ideas para incrementar el rendimiento eficientemente en cuanto a la energía consumida: (1) encadenamiento (chaining) desde la jerarquía de memoria, (2) reenvío (forwarding) directo de los resultados, y (3) instrucciones de memoria "shape", con patrones de acceso complejos. Además, esta tesis presenta dos herramientas para medir y analizar lo apropiado de usar microarquitecturas vectoriales para una aplicación. La primera herramienta es VALib, una biblioteca que permite la vectorización manual de aplicaciones, cuyo propósito principal es el de recolectar datos para una caracterización detallada a nivel de instrucción, así como el de generar trazas para la segunda herramienta, SimpleVector. SimpleVector es un simulador rápido basado en trazas que estima el tiempo de ejecución de una aplicación vectorial en la microarquitectura vectorial candidata. Finalmente, la tesis también evalúa las características del procesador Knight's Corner, con unidades SIMD en orden sencillas. Lo aprendido en estos análisis se ha aplicado en el diseño integrado.

Abstract:
A model of dark matter excitations is studied in an attempt to explain the anomalously large 511 keV photon line emission observed by the SPI spectrograph on INTEGRAL to be originating from the galactic bulge of the Milky Way. The proposed dark matter WIMP has a near degenerate mass partner a few MeV heavier. Scattering between dark matter particles leads to excitations, with the subsequent decays producing an electron-positron pair. In this way, the kinetic energy of the massive dark matter particles can be efficiently converted into electron-positron pairs moving slow enough to produce the narrow annihilation line observed. With a sufficiently large mass gap, kinematic considerations and the cuspy dark matter density profile constrain excitations to the galactic bulge where the escape velocity, and thus the fraction of dark matter particles above the kinematic cutoff, is large.
Un model d'excitations matière sombre est etudié dans une tentative d'explication de la ligne d'emission anormalement large observé par le spectrographe SPI sur INTEGRAL originaire du bulbe galactique de la Voie Lactée. La matière sombre WIMP proposée possède un partenaire ayant une masse de quelques MeV supplémentaires. La diffusion entre les particules de matière sombre mène aux excitations et à la désintégration ultérieure en une paire électron-positron. De cette façon, l'énergie cinétique des particules de matière sombre peut être convertie en paires électron-positron se déplaçant suffisement lentement pour produire l'étroite ligne d'annihilation observée. Avec un espacement en masse suffisement grand, les considérations cinématique et un profil de densité de la matière sombre cuspy contraignent les excitations au bulbe galactique, où la vitesse d'échappement, et donc la fraction de particules matière sombre au-dessus du seuil cinétique, est grande.

Abstract:
ABSTRACT Designing Anti-Islanding Detection Using the Synchrophasor Vector Processor Ruth Huang The need for distributed generation (DG) has become more and more popular because of the adverse effects of fossil fuels and the fear of running out of fossil fuels. By having DG, there are less transmission losses, voltage support, controllability of the system, decreased costs in transmission and distribution, power quality improvement, energy efficiency, and reduced reserve margin. The adverse effects of DG are voltage flicker, harmonics, and islanding. Islanding occurs when the DG continues to energize the power system when the main utility is disconnected. Detecting islanding is important for personnel safety, speedy restoration, and equipment protection. This paper describes the different islanding methods currently used and the benefits of combining two passive islanding detection methods, under/over voltage detection and voltage phase jump detection methods, using the synchrophasor vector processor (SVP).

Abstract:
This dissertation describes a theoretical and experimental study on coherent thermal emission from thin-film multilayer structures. A novel multilayer structure consisting of a one-dimensional photonic crystal and a polar material (or a metal) is proposed as a coherent thermal-emission source. Surface electromagnetic waves can be excited at the edge of photonic crystal, enabling coherent emission characteristics (i.e., spectral- and directional-selectivity in the emissivity). A near-infrared coherent emission source is designed and fabricated using vacuum deposition and chemical vapor deposition techniques. Measurements were performed using a Fourier-transform infrared spectrometer and a laser scatterometer. The agreement between the resonance conditions obtained from experiments and the calculated dispersion relation confirms that surface waves at the photonic crystal-metal interface can be utilized to build coherent thermal-emission sources. The second part of this dissertation focuses on the energy propagation direction in near-field thermal radiation. The energy streamline method based on the Poynting vector is applied to near-field thermal radiation by incorporating the fluctuational electrodynamics, in which thermal emission is viewed as originated from random motion of electric dipoles at temperatures above absolute zero. It is shown that the Poynting vector is decoupled for each parallel wavevector component due to the randomness of thermal emission. The spectral radiative energy travels in infinite directions along curved lines; this is a fundamental characteristic of near-field thermal radiation. The findings in this dissertation are important for the design of near-field optical sensors and energy conversion devices.

Abstract:
In the present paper, we investigate the energy propagation direction in near-field thermal radiation between two semi-infinite surfaces separated by a vacuum gap. Based on the fluctuational electrodynamics, we demonstrate in detail that Poynting vectors for each parallel wavevector component (β) are decoupled due to the randomness of thermal radiation. The results reveal that the spectral radiative energy is transferred in infinite directions. By separately tracing the Poynting vector for each given β, the energy propagation direction in the vacuum gap is visualized. Depending on β values, there exist considerable lateral shifts of the energy streamline. The range of β values dominantly contributing to the spectral energy flux is identified for different wavelengths. Furthermore, the effect of surface polaritons on the lateral shift is also discussed.

Abstract:
With the energy saving concerns, microwave heating method becomes much attention in heating process of various applications. Depending on applicator geometry design, type of work load, and position in a microwave heating system, it can save energy 20% to 40% more than the energy consumed by a conventional heating method. However, it is difficult to achieve this energy saving for low dielectric constant workload that cannot perform as a self-dielectric resonator (DR) load. This paper aspires to propose a new method of inserting reflector into the low dielectric constant load to enhance energy absorption rate under the microwave irradiation process. The spatial electromagnetic fields (E-field and H-field) patterns of this workload and applicator were simulated with the commercial HFSS software. By using the Poynting vector theorem, the dissipation power intensity can be calculated from the electromagnetic field and it is integrated to the second order heat transfer equation. The numerical temperature distribution result was resemblance with the experimental result. From both numerical and experimental results, the energy absorption rate of workload can be improved obviously by using a reflector as compared to the rate without using the reflector for low dielectric constant.

Abstract:
In this work, we investigated the reflection properties of artificial opals composed of submicron silica spheres with diverse structural parameters and under the effect of light in different states. Furthermore, the primary rules how the reflection properties of artificial opals convert as these factors changing have been revealed clearly. These factors can take effects in changing the shape, value, and position of the peak of the hemispherical reflectance of artificial opals. Then we got the distribution and propagation process of the Poynting vectors corresponding to the positions of the diffraction peak and the low reflectance in the artificial opals at normal and oblique incidence of P-polarization. Comparing with the theoretical interpretation which is a little complicated and nonobjective, this paper will provide a visual result to explain the reason why the structure has high reflectance in some spectral ranges.

Abstract:
Traumatic brain injuries (TBI) due to blast are common in modern combat situations, and often lead to permanent cognitive impairment. Despite the prevalence and severity of blast-induced TBI, the condition remains poorly understood. Computer simulations of blast and blast injury mechanics offer enormous potential; however, computer models require accurate descriptions of tissue mechanics and boundary conditions in vivo. To gain insight into the mechanisms of blast injury, we applied direct (light) oscillatory pressure loading to the skulls of human volunteers, and measured displacement and strain fields using the methodology of magnetic resonance elastography (MRE). MRE is a non-invasive imaging modality that provides quantitative spatial maps of tissue stiffness. MRE is performed by inducing micron-amplitude propagating shear waves into tissue and imaging the resulting harmonic motion with standard clinical MRI hardware. Shear waves are initiated by an MR-compatible actuator and detected by a specialized “motion-sensitive” MRI pulse sequence (software). Motion sensitized MR images provide displacement field data which can be inverted to estimate material stiffness by invoking a restricted form of Navier’s equation. Clinical interest in MRE has largely been driven by the empirical relationship between tissue stiffness and health. However, the “raw” MRE data (3-D displacement measurements) themselves can elucidate loading paths, anatomic boundaries and the dynamic response of the intact human head. In this study, we use the MRE imaging technique to measure in vivo displacement fields of brain motion as the cranium is exposed to acoustic frequency pressure excitation (45, 60, 80 Hz) and we calculate the resulting shear-strain fields (2-D). We estimate the Poynting vector (energy flux) field to illuminate the directions of internal wave propagation, and to identify the energy absorbing and reflecting regions within the brain.

Abstract:
This paper describes a theoretical investigation of near-field radiative heat transfer between doped silicon surfaces separated by a vacuum gap. Using an improved dielectric function model for heavily doped silicon, along with fluctuation-dissipation theorem, and dyadic Green’s function, the present authors calculated the energy transfer between the doped silicon surfaces near room temperature. The effects of doping level, polarization, and width of the vacuum gap on the overall radiative transfer were investigated. It was observed that increase in the doping concentration of the emitter does not necessarily enhance the energy transfer in the near field. The energy-streamline method was used to model the lateral shift of the energy pathway, which is the trace of the Poynting vectors in the vacuum gap. The analysis performed in this study may facilitate the understanding of near-field radiation for applications such as thermal management in nanoelectronics, energy conversion systems, and nanothermal manufacturing.

Abstract:
This work numerically investigated the interaction between two resonances: the magnetic polariton (MP) and surface plasmon polariton (SPP). A reflectance contour plot of deep silver slit arrays quantitatively identified the MP mode and the SPP excitation’s dependence on the period. Five arrays were selected for their SPP excitation wavenumber that approached and then diverged from that of an MP mode. Reflectance spectra from arrays showed dips associated with the two resonances between 10000 cm−1 and 25000 cm−1. Both the magnitude and corresponding wavenumber of nearby dips were modified by the interaction. Moreover, a third dip might appear or two dips might merge into a wider valley when two resonance excitation wavenumbers are close enough. The interaction was further elucidated with electromagnetic fields, Poynting vectors, and the energy density corresponding to representative reflectance dips.
