The following sections are included:

• Contents

This book presents the first self-contained introduction to a newly shaping branch of applied physics on the frontier between modern photonics, electromagnetics, acoustics of heterogeneous media, and design of heterogeneous metamaterials and nanostructures with special properties unattainable in nature. This branch opens up the new avenues in the creation of miniaturized subwavelength systems, governing wave flows by means of gradient metamaterials characterized by technologically controlled smooth spatial distributions of dielectric or elastic parameters. Some results, obtained in these fields on a case-by-case basis, were dispersed hitherto in a number of journals devoted to quantum electronics, optics, radiophysics and material science; this work revealed the appearance of overlapping problems…
