Abstract

Reflection and transmission of plane waves due to a truncated anisotropic chiral slab are studied, and followed by a uniform asymptotic solution of the diffraction contribution within the physical optics approximation. The material is characterized by a chirality parameter and possesses an optical axis normal to the planar surfaces. The structure is surrounded by free space and the incidence direction is oblique with respect to the edge. A bounce diagram approach is applied to evaluate reflection and transmission matrices related to the ordinary plane of incidence. The uniform asymptotic physical optics approach is then exploited to obtain the diffraction matrix to be used in accordance with the uniform geometrical theory of diffraction. The proposed solution is validated via comparisons with a full-wave electromagnetic solver. © 1963-2012 IEEE.
