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.
