On zero-reflection and zero-transmission of a stratified lossy medium

Abstract

In this paper a method to analyze the zero-reflection and zero-transmission conditions through a stratified lossy medium, is presented. The interaction of the electromagnetic radiation with the stratified material is taken into account by means of the transfer-matrix approach. The complex plane-wave propagation vectors are represented with the complex-angle formulation. In order to obtain these zero conditions an adaptive method has been adopted. A numerical code has been implemented to compute the field all-over the space. Some numerical applications, in order to obtain an electric matching layer for a large range of angles, are presented. This approach can be easily extended to an arbitrary number of layers to realize an intermediate layer with exotic properties.
