Some Aspects of Radio Wave Propagation in Double Zero Metamaterials Having the Real Parts of Epsilon and Mu Equal to Zero

Abstract

Recently, various uncommon materials such as metamaterials have been the subject of intensive research. In this paper, we introduce a new class of materials called double zero materials (DZR) having the real parts of both its epsilon and mu equal to zero and investigate the electromagnetic wave propagation in them, particularly the propagation constant k and intrinsic impedance η. We investigate the reflection and transmission coefficients from multilayer structures made of DZR material located in various media. It is shown that the DZR constants namely k and η and also the reflection and transmission coefficients from the multilayer structures are all real quantities. Several numerical examples are provided for both dispersive and nondispersive DZR materials.
