Evanescent electromagnetic wave conversion apparatus and methods

TLDR
In this article, the authors provide an approach for the conversion of evanescent electromagnetic waves to non-evanescent ones by using an artificially-structured material such as a layered structure or other metamaterial.
Abstract
Apparatus, methods, and systems provide conversion of evanescent electromagnetic waves to non-evanescent electromagnetic waves and/or conversion of non-evanescent electromagnetic waves to evanescent electromagnetic waves. In some approaches the conversion includes propagation of electromagnetic waves within an indefinite electromagnetic medium, and the indefinite medium may include an artificially-structured material such as a layered structure or other metamaterial.

Systems and methods for transmitting electromagnetic energy in a photonic device

TL;DR: In this paper, the authors describe a system that allows transmission of an electromagnetic wave in and through a periodic multilayered photonic device, which is a periodic stack of plane-parallel layers with at least one of them displaying dielectric anisotropy with a principle anisotropic axis forming an oblique angle with the normal to the layers.
