This book opens a new avenue to an engendering field of applied physics, located at the "crossing" of modern photonics, electromagnetics, acoustics and material science. It also highlights the ...concept of "non-locality", which proves to be not a special feature of quantum phenomena, but is shown to have an important counterpart in classical physics and its engineering applications too. Furthermore, it visualizes the physical results by means of simple analytical presentations, reduced sometimes to the elementary functions.Contents:IntroductionNon-local Dispersion of Heterogeneous DielectricsGradient Photonic Barriers: Generalizations of the Fundamental ModelResonant Tunneling of Light Through Gradient Dielectric NanobarriersInteraction of Electromagnetic Waves with Continuously Structured DielectricsPolarization Phenomena in Gradient NanophotonicsGradient Optics of Guided and Surface Electromagnetic WavesNon-local Acoustic Dispersion of Gradient Solid LayersShear Acoustic Waves in Gradient Elastic SolidsShear Horizontal Surface Acoustic Waves on Graded Index MediaReadership: For researchers, engineers and designers of communication systems, lecturers and graduate students.

Straipsnyje apžvelgiamos R. Descartes‘o spręstos matematinės ir gamtamokslinės problemos, aptariami jo gauti rezultatai ir jų poveikis mokslų raidai. Jis pasižymėjo matematikoje, daugelyje fizikos ...sričių, meteorologijoje, fiziologijoje. R. Descartes sugalvojo algebrinę lygtį atvaizduoti stačiakampėje koordinačių sistemoje. Į geometriją įsiveržus algebrai, jos problemos pradėtos spręsti analitiškai. Tai lėmė tolesnę matematinės analizės raidą. Optikoje R. Descartes‘ui pavyko išaiškinti vaivorykštės prigimtį ir įrodyti, kad optikos prietaisams tinkamiausi ne sferiniai, bet hiperboliniai lęšiai. Siekdamas universaliais principais paaiškinti gamtos reiškinius, R. Descartes įvedė į mokslinę vartoseną gamtos dėsnio sampratą. Jis buvo racionalistinio – deduktyvaus arba aksiominio – fizikos teorijų konstravimo pradininkas. Tokiu metodu gautus dėsnius R. Descartes reikalavo patikrinti eksperimentu.
This book introduces the fundamental mechanism of photonic glasses — the linear and nonlinear optical effects in glass under intense light irradiation: phot-induced absorption, refraction, ...polarization, frequency, coherence and monochromaticity changes. Emphasis is placed on new developments in the structure, spectroscopy and physics of new glassy materials for photonics applications, such as optical communication, optical data storage, new lasers and new photonic components and devices. The book presents the research results of the authors in new glasses for photonics over the last decade.
This book presents a substantial description of the principles and applications of digital holography. The first part of the book deals with mathematical basics and the linear filtering theory ...necessary to approach the topic. The next part describes the fundamentals of diffraction theory and exhaustively details the numerical computation of diffracted fields using FFT algorithms. A thorough presentation of the principles of holography and digital holography, including digital color holography, is proposed in the third part. A special section is devoted to the algorithms and methods for the numerical reconstruction of holograms. There is also a chapter devoted to digital holographic interferometry with applications in holographic microscopy, quantitative phase contrast imaging, multidimensional deformation investigations, surface shape measurements, fluid mechanics, refractive index investigations, synthetic aperture imaging and information encrypting. Keys so as to understand the differences between digital holography and speckle interferometry and examples of software for hologram reconstructions are also treated in brief.Contents1. Mathematical Prerequisites. 2. The Scalar Theory of Diffraction. 3. Calculating Diffraction by Fast Fourier Transform. 4. Fundamentals of Holography. 5. Digital Off-Axis Fresnel Holography. 6.

Written by renowned experts in the field of photon management in solar cells, this one-stop reference gives an introduction to the physics of light management in solar cells, and discusses the ...different concepts and methods of applying photon management. The authors cover the physics, principles, concepts, technologies, and methods used, explaining how to increase the efficiency of solar cells by splitting or modifying the solar spectrum before they absorb the sunlight. In so doing, they present novel concepts and materials allowing for the cheaper, more flexible manufacture of solar cells and systems. For educational purposes, the authors have split the reasons for photon management into spatial and spectral light management. Bridging the gap between the photonics and the photovoltaics communities, this is an invaluable reference for materials scientists, physicists in industry, experimental physicists, lecturers in physics, Ph.D. students in physics and material sciences, engineers in power technology, applied and surface physicists.
