提出了一种新的基于拉伸坐标的完全匹配层（SCB PML）的实现方法，用于传输线模型（TLM）中的波导端接结构。一个广义的SCB PML，复频移PML（CFS PML）也实现了研究其性能的倏逝波。采用Z域中的状态变量来获得入射电压脉冲的更新方程。数值结果的矩形波导填充有损耗介质以及自由空间，并为平行板波导。版权所有© 2004年约翰威利父子有限公司。
A novel implementation of the stretched co‐ordinate‐based perfectly matched layer (SCB PML) is presented to terminate waveguide structures in transmission‐line modelling (TLM). A generalized SCB PML, the complex frequency shifted PML (CFS PML) is also implemented to investigate its performance for evanescent waves. State variables in the Z‐domain are employed to obtain update equations for incident voltage pulses. Numerical results for a rectangular waveguide filled with a lossy medium as well as free space, and for a parallel plate waveguide are presented. Copyright © 2004 John Wiley & Sons, Ltd.
