Unified analysis of perfectly matched layers using differential forms

Research output: Contribution to journalArticlepeer-review


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 the electromagnetic fields and exploring the metric invariance of Maxwell's equations, the various prevalent PML formulations (Maxwellian and non-Maxwellian) are unified. The analysis also reveals that other PML formulations are also possible, embodying the previous PML formulations as special cases.
