Abstract

Reflection of electromagnetic plane wave from a planar chiral nihility-chiral nihility interface is calculated as a special case of two different chiral media by assuming that permittivities and perme-abilities of the both media approach to zero. That is, ε_i→0, μ_i→0, and chiralities κ_i≠0, i=1, 2. These results are used to find the geometrical optics reflected fields of a cylindrical chiral nihility-chiral nihility interface, when it is excited by a plane wave. Using the Maslov's method, field expression which yields finite values around the focus of cylindrical interface is also determined.
