A HYBRID METHOD FOR TE SCATTERING BY A PERFECTLY CONDUCTING SEMICYLINDER

Bistatic scattering of a perfectly conducting semicylinder is analysed by using a hybrid method. In the hybrid method, the currents in the close vicinity of edges are represented as unknown coefficients; the first-order currents on the curved face are obtained by Fock theory; the high-order currents are described as the Fock type functions involving two unknown coefficients. The first-order currents on planar surface are physical optical currents and diffraction currents obtained by the uniform geometrical theory of diffraction form involving two unknown coefficients. The magnetic field equation is solved to obtained four coefficients and the currents in the close vicinity of the edges. The results obtained by the hybrid method are in good agreement with the results of moment method.
