Diffraction of obliquely incident plane waves by resistive and conductive planar surfaces

The multiple diffraction of obliquely incident plane waves by the three-part resistive and conductive plane is evaluated via uniform asymptotic high frequency analysis. This analysis is based on a spectral iteration technique consisting of employing the Fourier Integral representation of the diffracted field through the solution of a pair of uncoupled Wiener-Hopf equations. By studying these equations iteratively, the double and triple diffracted fields are obtained through the saddle-point technique. Some numerical examples are also presented.
