大统计斜率随机表面光散射的Monte Carlo数值模拟

Monte Carlo Simulation of Scattering from Random Surfaces with Large Statistical Slopes

本文在Ｋｉｒｃｈｈｏｆ近似的基础上，通过ＭｏｎｔｅＣａｒｌｏ数值模拟，分析了大统计斜率随机表面的单次和二次散射。数值结果证明了导体和介质表面均存在起因于多次散射的后向增强散射，入射光的偏振状态对介质表面散射特征有明显的影响。数值结果与实验报导有很好吻合。

Single and double scattering from random surfaces with large statistical slopes were investigated by Monte Carlo simulation based on Kirchhoff approximation.Enhanced backscattering was proved to be a result of multiple scattering for both conductive and dielectric surfaces and scattering characteristics of dielectric surfaces were shown to be significantly influenced by the polarization state of incident light.Numerical results were in good agreement with experimental reports.
