Scattering from a Perfectly Conducting Plate Using Wire-Grid and MoM with Pulse Basis Functions

This paper analyzes the scattering characteristics from a solid perfectly conducting flat plate. Different plates with different incident plane waves are considered. Radar cross sections including the monostatic and bistatic ones are obtained and compared for all structures. The efficiency of using a developed wire grid code based on the method of moments with pulse basis functions is proved by comparing its results with those published in other works and obtained experimentally and numerically using the method of moments with different schemes and basis functions. It is revealed that the considered model and the code developed on its base can be effectively used in the future for modeling of complex wire grid and solid scatterers and even for creating new sparse ones based on the agreement found in the scattering field calculations.
