The Perfectly Matched Layer for Computational Acoustics
Recently, Berenger  formulated, for the finite difference — time domain solution of Maxwell’s equations in two dimensions, a new absorbing boundary, which he called a perfectly matched layer (PML). His demonstration that the PML possesses extraordinary energy-absorbing properties was verified by Katz, et al. , who also extended the formulation to three-dimensions.
