DIFFRACTION COEFFICIENT FOR A HALF-PLANE WITH ANISOTROPIC CONDUCTIVITY

The diffraction of obliquely incident plane waves by a half-plane havi ng anisotropic conductivity is investigated. The half-plane is assumed to be perfectly conducting in one direction and to have finite conduc tivity in the transverse direction. The material of the halfplane is s imulated by a resistive-type boundary condition with the resistivity b eing a constant tensor. By using the Fourier transform technique, the problem is formulated into a pair of simultaneous Wiener-Hopf equation s which are decoupled by means of a polynomial transformation and then solved by standard techniques.
