Abstract
We investigate the two-dimensional (2-D) perfectly matched layer (PML) models reformulated from the 3-D PML model originally developed by Cohen and Monk in 1999. We propose the discontinuous Galerkin methods for solving both 2-D TMz and TEz models. We establish the proofs of the stability and error estimate for the proposed schemes. Finally, numerical results are presented to demonstrate the accuracy and performance of our method. (C)& nbsp;2021 Elsevier B.V. All rights reserved.
