WIENER-HOPF TECHNIQUE AND SOME SPECIAL GEOMETRIES

Abstract

It is not always possible to obtain rigorous analytical solutions to diffraction problems because of geometrical and physical complexity of most scattering surfaces. Wiener-Hopf (WH) method is applicable to plane discontinuities like two or three –part plane problems, open structures like an infinite set of parallel half-planes and closed structures like parallel plate waveguide. The main purpose of this study is to give an overview of the Wiener-Hopf technique, related factorization and decomposition methods. In order to outline the theory, five types of Wiener-Hopf geometries and solution methods for the diffraction of electromagnetic waves from these geometries were investigated.
