摘要

本文对无条件稳定相关赫米特时域有限差分法实现了完全匹配层(PML)吸收边界条件。这使得分析电磁散射问题具有很高的灵活性，可以使用更有效的吸收边界条件来截断计算域。最后给出了二维矩形损耗介质散射的数值算例，验证了该方法的有效性和准确性。

Perfectly matched layer absorbing boundary conditions for AH FDTD method

In this paper, a perfectly matched layer (PML) absorbing boundary condition are implemented for the unconditionally stable Associated Hermite (AH) FDTD method. This leads to a high flexibility to analyze electromagnetic scattering problems, in terms of using a more efficient absorbing boundary condition to truncate computational domain. A numerical example of scattering from a 2-D rectangular loss dielectric medium is presented to validate the efficiency and accuracy.
