Abstract

Two-dimensional diffraction of an H-polarized electromagnetic plane wave by a slit embedded in an anisotropic medium is studied. The problem is formulated using the discontinuity characteristic of the Weber-Schafheitlin integral (WSI), and expressions for the diffracted fields and the surface wave trapped in the vicinity of the conducting screen are derived. The numerical results for the radiation pattern of a diffracted field are presented. The pattern is found to show an asymmetry for normal incidence. The solutions are valid for arbitrary small slit width and arbitrary anisotropy.
