摘要
本文主要采用矩量法(method of moment MOM)研究了分层粗糙面的电磁散射特性,首先给出了该散射问题的积分方程和矩阵方程,然后通过与时域有限差分(finite difference time domain FDTD)计算结果的对比说明了本文所提算法的有效性,最后讨论了分层粗糙面的均方根高度、相关长度以及两层粗糙面之间的距离对双站散射系数的影响。
The properties of the electromagnetic scattering from two-layered rough surface have been investigated in this paper through the method of moment（MOM）.The integral equations and the matrix equations for solving this scattering problem have been provided firstly.The validity of this approach has been shown by comparing the numerical results to the finite difference time domain（FDTD）technique.Finally, several numerical results are illustrated to discuss the influences of the root mean square height, the correlation length, and the average height between the two rough surfaces on the bistatic scattering coefficient.
