| 摘 要： | 把广义最小余数法(GMRES)和矩量法(MOM)结合起来研究三维介质目标的电磁散射问题。对三维介质目标的远区散射场进行了计算,结果与高斯消去法和共轭梯度法(CGM)的计算结果进行了比较,它们吻合的很好,而GMRES方法的计算效率大大提高,说明GMRES方法和MOM的结合是求解三维电磁散射问题的有效途径之一。

| Abstract: | 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. |
