摘要对离散源法(DSM)进行了改进，使之能够分析部分嵌入衬底的轴对称可穿透纳米粒子的偏振光散射。新的DSM数值格式能够考虑平面颗粒、丘状、凹坑和空洞等衬底缺陷的散射。文中给出了数值格式的详细描述。所开发的计算机模型已被用于研究浅颗粒和凹坑的散射。给出了P/S偏振光的微分散射截面和积分响应的模拟结果。
Abstract The Discrete Sources Method (DSM) has been modified to analyze polarized light scattering by an axial symmetri c penetrable nanoparticle partially embedded into a substrate. The new numerical scheme of the DSM enables to consider scattering from such substrate defects as flat particles, mounds, pits and voids. A detailed description of the numerical scheme is provided. The developed computer model has been employed to investigate scattering from a shallow particle and pit. Simulation results corresponding to the Differential Scattering Cross-Section and the integral response for P/S polarized light are presented.
