Abstract
The perfectly matched layer (PML) concept is interpreted as a change in the metric of space. By using the language of differential forms applied to th e electromagnetic fields and exploring the metric invariance of Maxwell's e quations, the various prevalent PML formulations (Maxwellian and non-Maxwel lian) are unified. The analysis also I reveals that other PML formulations are also possible, embodying the previous PML formulations as special cases . (C) 1999 John Wiley & Sons, Inc.
