ABSTRACT

A number of scattering and diffraction problems concerning semi infinite wave guides
have been solved by many authors and for many years. Theoretical analysis of
electromagnetic wave scattering and diffraction problems has been investigated
extensively with regard to a number of scatterers which have physical and geometrical
discontinuities.

As is well-known, Sommerfeld introduced the exact solutions to the diffraction by a
wedge by defining the idea of multiple-valued functions. His method is known as the
Sommerfeld theory of diffraction which is commonly defined for diffraction by Wedge-
Shaped obstacles. Wiener-Hopf showed that a certain singular integral equation could
be solved exactly using the theory of Complex Fourier transforms and functions of a
complex variable. This method of solution is known as the Wiener-Hopf technique.
Multiple diffraction of electromagnetic waves due to physical and geometrical
discontinuity is creating surface waves which are still dominant in communication
phenomena. Surface waves and related currents are analyzed by using Wiener-Hopf
technique in detail.
