MieSolver provides an efficient solver for the problem of wave propagation through a heterogeneous configuration of nonidentical circular cylinders. MieSolver allows great flexibility in the physical properties of each cylinder, and the cylinders may have opaque or penetrable cores, as well as an arbitrary number of penetrable layers. The wave propagation is governed by the two-dimensional Helmholtz equation and models electromagnetic, acoustic, and elastic waves. The solver is based on the Mie series solution for scattering by a single circular cylinder and hence is numerically stable and highly accurate. We demonstrate the accuracy of our software with extensive numerical experiments over a wide range of frequencies (about five orders of magnitude) and up to 60 cylinders.

MieSolver 为波通过异质圆柱体的异构配置的传播问题提供了一种有效的求解器。MieSolver 允许每个圆柱体的物理特性具有很大的灵活性，并且圆柱体可能具有不透明或可穿透的核心，以及任意数量的可穿透层。波传播受二维亥姆霍兹方程控制，并对电磁波、声波和弹性波进行建模。该求解器基于单个圆柱体散射的 Mie 级数解，因此数值稳定且精度高。我们通过在广泛的频率范围（大约五个数量级）和多达 60 个气缸上的大量数值实验证明了我们软件的准确性。
