| 摘 要： | 从理论和数值模拟两个方面对超光滑表面的散射电磁场进行了分析研究。从极化电流源的散射出发，推导了基片表面背向散射电磁场的微分散射分布。通过与经典散射理论的比较，发现在入射角和散射角都较小时，结论与经典散射理论相一致，但是在入射角或者散射角较大时，两者存在差异，原因是理论中考虑了阴影遮蔽效应，导致了入射光或散射光必须透过两...

| Abstract: | A theoretical and numerical method is described for calculating the angle-resolved scattering.Comparing with classical scattering theory,we find the conclusion drawn in this paper coincidences well with that of classical theory when incidence angle and scattering angle are both small,but they are different when incidence angle or scattering angle is large,which is caused by shielding effect of surface topography.Through theoretical analysis and numerical simulation,the theory in this paper is found to fit well with scatter measurement of super-smooth surface. |
