摘要
文章对时域有限差分法常用吸收边界的性能进行了分析,包括Mur吸收边界、PML(Perfectly Matched Layer)、UPML(Uniaxial PML)以及CPML(Convolution PML)。首先,简要介绍了几种吸收边界的理论基础;然后,根据前面理论进行Matlab仿真,通过采样二维情况下的高斯源和正弦源激励的电场值,分析比较4种吸收边界的性能;最后,总结了各种吸收边界的优劣和特点。
The performances of absorbing boundaries used commonly in FDTD, including Mur absorbing boundary, PML, UPML, CPML, were analyzed in this paper. Firstly, the theoretic foundations of this several absorbing boundaries were introduced briefly. Then, the performances were simulated using Matlab based on the first part by capturing the electric fields of Gauss source and sine source, respectively. Finally, the characteristics of the four kinds of absorbing boundaries were summarized.
