✦ Synopsis

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.
