Analysis of the field focused by hyperbolic lens embedded in chiral medium

Abstract

This paper is a theoretical investigation and analysis of the focal region fields of a hyperbolic focusing lens embedded in chiral medium. Chiral-dielectric and dielectric-chiral interfaces are studied and the behavior of waves after passing through these interfaces are discussed. Geometric optics (GO) is used initially. However, it fails around the focal region because it gives non-realistic singularity in this region. So, Maslov's method is used in the caustic region and the field analysis is made. The effect of chirality variation on the amplitude of the fields around the focal region is given and discussed.
