High frequency expressions for the field in the caustic region of a parabolic reflector coated with isotropic chiral medium

摘要

High frequency field expression for a parabolic reflector are derived using Maslov's method. Parabolic reflector has been coated with isotropic and homogeneous chiral medium. The effects of thickness of chiral layer, chirality parameter of the chiral medium and permittivity of the medium are studied.
