| 摘 要： | 完全匹配层(PML)良好的吸波特性已成功地用于FDTD问题。Katz给出了三维问题分量场所满足的12个微分方程,但未对波在PML中的传播特性进行讨论。本文基于Katz的微分方程组,推导出了平面波解、波数及其阻抗。

| Abstract: | The Perfectly Matched Layer(PML)is very effective in absorbing propagating wave, so that it has been successfully applied in FDTD research. Katz(1994) derived 12 differential equations in three-dimensional PML, but there is no conclusion for the propagation characters of plane wave in PML such as wave expression ,wave number and wave impedance. These characters are investigated in this paper. |

| Keywords: | Perfectly matched layer Absorbing boundary conditions Finite difference time domain Truncation |
