Abstract
Berenger's perfectly matched layer (PML) absorbing boundary condition is implemented for the first time in a TLM mesh. This is achieved thro ugh a special interface between the FDTD-PMLs and the TLM lattice. App lication to rectangular waveguides yields reflections less than -50dB at frequencies up to six times the cutoff frequency. These absorbing b oundary conditions are compared with one-way equation absorbing bounda ry conditions and with matched layers having only electric losses.
