Abstract
High frequency electromagnetic field expressions are analyzed for the focal region of a circular reflector coated with chiral medium. Maslov's method has been used for the study of focal region fields because geometrical optics is an approximate method and fails at the focal points. The effects of chirality parameter, thickness of chiral coating and permittivity of the medium on the focused fields are observed. It is concluded from the results that focused field strength increases with increase in chirality parameter, relative permittivity and thickness of the chiral coating.
