Wiener-Hopf analysis of the vector diffraction problem for a cylindrical waveguide cavity

The analysis of electromagnetic wave scattering by open-ended metallic waveguide cavities has received much attention in connection with the prediction and reduction of the radar cross section (RCS) of a target. This problem serves as a simple model of duct structures such as jet engine intakes of an aircraft and cracks occurring on surfaces of general complicated bodies. We consider the vector diffraction by a cavity formed by a semi-infinite circular waveguide with an interior planar termination as a generalization of our previous scalar problems, and analyze the non-symmetric electromagnetic wave diffraction by means of the Wiener-Hopf technique
