Application of GMRES to electromagnetic scattering problems from three-dimentional dielectric scatterer

XIA Hao-miao, SUN Yu-fa,SONG Kai-hong(Insifute of Electronic Science and Technology, Anhui University, Hefei230039, China)  
The electromagnetic scattering of three-dimentional dielectric body is investigated by using a mixed method of Generalized Minimal Residual (GMRES) and the method of moments (MOM).The numerical results of the far scattered fields obtained by the presented method are in good agreement with results achieved by Gaussian elimination method and conjugate gradient method (CGM), while the computation efficiency is considerably improved. It is shown that the mixed method of GMRES and MOM is one of the effective methods to solve the problem of electromagnetic scattering from 3D dielectric scatter.
