Abstract

The spatial decomposition technique is successfully implemented to analyze electromagnetic scattering by both two-dimensional and three-dimensional perfectly conducting and dielectric scatterers. Two canonical scattering cases are reported. Electromagnetic scattering by electrically large two-dimensional perfectly conducting thin strip scatterers is illustrated. The distribution of the bistatic radar cross section for a 10λ strip scatterer with transverse magnetic excitation is also given. The strip scatterer is divided into 10 subzones for implementation of the spatial decomposition technique. The spatial decomposition data for the first sweep are compared. Results of the monostatic radar cross section are given for the same scatterer, but with transverse electric excitation. Good agreement with the direct method-of-moments solution is also shown.
