Popis:	Finite element method (FEM) is combined with volumetric plane-wave excitation method (VPWE) and total-and scattered-field decomposition(TSFD)technique is used to analyze some electromagnetic scattering of typical 3-D objects in this paper. The whole computational area is decomposed into total-field and scattered-field. And then, the incident wave is impressed in the whole total-field region. The detailed algorithms of VPWE-TSFD/FEM are presented. Radar cross sections (RCS) of some typical objects are computed, which demonstrate that the given method is effective for electromagnetic scattering analysis of 3-D objects.
