Analysis of Focal Region Fields of PEMC Gregorian System Embedded in Homogeneous Chiral Medium

Abstract
This paper presents the high frequency electromagnetic field expressions for perfect electromagnetic conductor (PEMC) Gregorian system. In this Gregorian system both the reflectors are PEMC and are embedded in homogenous chiral medium. Depending upon the values of chirality parameter (kβ) two cases are analyzed. In the first case, chiral medium supports positive phase velocity (PPV) for both the left circularly polarized (LCP) and right circularly polarized (RCP) modes. In the second case, chiral medium supporting PPV for one mode and negative phase velocity (NPV) for the other mode is taken into account. Since geometrical optics (GO) fails at the focal point, so Maslov's method is used to find the field expressions at the focal point. Field plots for different values of admittance (M) of the PEMC and the chirality parameter (kβ) are given in the paper.
