HELIOS：用于均匀、周期和分层环境中光散射的面积积分方程软件
摘要
我们 presented HELIOS（HomogEneous and Layered medIa Optical Scattering），一个开源的面积积分方程（SIE）软件，旨在建模嵌入均匀或层状介质和周期背景中的粒子的光散射。该代码实现了 Poggio-Miller-Chang-Harrington-Wu-Tsai（PMCHWT）配方，在求解含有可渗透物体的散射问题方面已显示出卓越的可靠性。域边界使用三角网格离散化，Upon which the electric and magnetic surface current densities are expanded using the Rao-Wilton-Glisson (RWG) basis functions。对于周期结构，如光子晶体和超透镜表面，HELIOS 使用 Ewald 的变换有效地评估与 2D 晶格相关的无穷级数。Regarding stratified media, the code utilizes a matrix-friendly approach for the layered media Green's tensor, computing Sommerfeld integrals and accelerating calculations through a tabulation-interpolation scheme。Source code is implemented in C++，while a Python interface manages the workflow, including simulation setup, solver run, and post-processing。演示了 HELIOS 在各种示例中的准确性和多功能性，这些示例涵盖了其所有功能。
