Some twenty years ago Berenger introduced theremarkable method of perfectly matchedlayers for truncating to a rectangle, the computation ofsolutions of Maxwell’s equations in 1+2 and 1+3 dimensionalspace time. Only recently have some of the fundamentalquestions concerning this method been resolved.For example the stability of the original methodand its perfection. We discuss the analysis of thisand related methods that are constructed to performbetter in variable coefficient settings where the perfectionof Berenger no longer holds. Research donewith Laurence Haplern, Sabrina Petit, and LudovicMetivier.
