perfectly matched layer

  • 完美匹配层:完美匹配层(PML)是一种用于波动方程的人工吸收层,常用于数值方法中截断计算区域以模拟具有开放边界的问题,特别是在FDTD和FE方法中。PML与普通吸收材料的关键区别在于,它被设计成从非PML介质入射的波不会在界面上反射,这个特性使得PML能够强烈吸收计算区域内部的出射波而不将其反射回内部。

Perfectly matched layer

  • abstract: A perfectly matched layer (PML) is an artificial absorbing layer for wave equations, commonly used to truncate computational regions in numerical methods to simulate problems with open boundaries, especially in the FDTD and FE methods. The key property of a PML that distinguishes it from an ordinary absorbing material is that it is designed so that waves incident upon the PML from a non-PML medium do not reflect at the interface—this property allows the PML to strongly absorb outgoing waves from the interior of a computational region without reflecting them back into the interior.
