Focal Region Fields of Cassegrain System Placed in Homogeneous Chiral Medium

Progress In Electromagnetics Research B, Vol. 21, 329-346, 2010
Abstract
In this paper the high frequency electromagnetic field expressions for two dimensional Cassegrain system embedded in a chiral medium are presented. Due to failure of Geometrical Optics (GO) at the caustic region, Maslov's method is used to find the field expressions. Two different cases have been analyzed. Firstly, the chirality parameter () is adjusted to support positive phase velocity (PPV) for both left circularly polarized (LCP) and right circularly polarized (RCP) modes traveling in the medium. Secondly, is adjusted such that one mode travels with PPV, and the other mode travels with negative phase velocity (NPV). The results for both cases are presented in the paper.
