Plane Wave Diffraction by PEC - DNG Metamaterial Junctions in Non-Planar Arrangements

Abstract

A high-frequency solution is presented to evaluate the diffraction contribution by the edge of a non-planar junction that consists of a metal layer and a lossy double negative metamaterial sheet. The diffraction problem is solved in the case of skew incidence by means of an analytical method that is based on the physical optics approximation and provides closed form expressions in the framework of the uniform theory of diffraction. The evaluation of the diffraction coefficients is stress-free since they contain standard parameters and functions.
