论文摘要
多个散射方法T-Matrix（MSTMM）可用于求解由许多紧凑型散射器组成的系统的电磁响应，同时使用相对较少的自由度保留了良好的准确性，在很大程度上超过了可以处理的散点器数量的其他方法。在这里，我们使用Ewald型晶格求和将方法扩展到无限的周期性结构，并利用结构的可能对称性来进一步提高其效率，以便可以相对轻松地研究包含数万个颗粒的系统。我们发布了该方法的现代实施，包括根据GNU通用公共许可证所提供的理论改进。
The multiple scattering method T-matrix (MSTMM) can be used to solve the electromagnetic response of systems consisting of many compact scatterers, retaining a good level of accuracy while using relatively few degrees of freedom, largely surpassing other methods in the number of scatterers it can deal with. Here we extend the method to infinite periodic structures using Ewald-type lattice summation, and we exploit the possible symmetries of the structure to further improve its efficiency, so that systems containing tens of thousands of particles can be studied with relative ease. We release a modern implementation of the method, including the theoretical improvements presented here, under GNU General Public Licence.
