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.
