Electromagnetic scattering from arbitrary flat plates: Analysis of the problem by using method of moments with different sinc type basis functions

In this paper, three dimensional electromagnetic scattering problem is solved by using pulse-sinc type basis functions in the Method of Moments (MoM) procedure. This method is applied to the scattering problems of a plane wave illuminated flat arbitrary geometries. Pulse-sinc based MoM formulation is developed, the current densities and radar cross section of different geometries are investigated. The radar cross section (RCS) for co-polarized and cross polarized cases of the flat plate geometries are compared with both of the results obtained from the sinc-sinc based formulation and SuperNEC. The results obtained by using pulse-sinc formulation are in very good agreement with those of the SuperNEC.
