| 摘 要： | 基于统计型积分方程方法(Stochastic Integral Equation Method, SIEM)实现了高斯粗糙面的高效散射计算.与传统求解随机粗糙面散射特性的蒙特卡洛法(Monte Carlo Method, MC)相比, 该方法采用统计面元格林函数, 考虑粗糙面高斯随机分布的场源耦合影响, 只需要计算一次矩阵元素和待求未知量, 提高了求解粗糙面问题的计算效率.数值结果显示, 文中方法与MC吻合, 计算效率得到显著提高.

| Abstract: | In this paper, we achieve the efficient computing of electromagnetic scattering for Gaussian rough surface based on the stochastic integral equation method(SIEM). Compared with the traditional method to solve the electromagnetic scattering the Monte Carlo method, SIEM only computes the matrix elements and the unknown current units once by using the statistical surface-unit Green's function to couple the field and source, which is very efficient. The numerical results coincide with the Monte Carlo method very well and the computational efficiency is greatly improved. |
