Scattering of Arbitrarily Polarized Plane Waves Obliquely Incident on Infinite Slots or Strips in a Planar-Stratified Medium

Page 1634.

Abstract:

An exact analysis of three-dimensional scattering by a slot or by a strip right on an interface between two adjacent layers of a planar stratified isotropic medium is presented. The most general case of arbitrarily polarized obliquely incident plane waves is considered. The formulation is based on systems of singular integral-integrodifferential equations (SIE-SIDE). These systems are discretized with the help of two independent algorithms recently developed in [1]. Filling up the matrix elements involves rapidly convergent spectral integrals. The expression of the far-radiated field is derived and numerical results are presented for several cases.
