Wiener-Hopf Analysis of the Plane Wave Diffraction by a Perfectly Conducting Rectangular Cylinder: The Case of H Polarization

The diffraction of an H-polarized plane electromagnetic wave by a perfectly conducting rectangular cylinder is rigorously investigated using the Wiener-Hopf technique. Exact and approximate solutions of the Wiener-Hopf equations are obtained. The scattered field is evaluated explicitly using the saddle point method. Representative numerical examples of the radar cross section are presented. Some comparisons with the existing results are also provided.
