A unified look at Berenger's PML for general anisotropic media

Abstract

The recently proposed general material-independent per- () fectly matched layer GMIPML and extended perfectly matched layer () EPML techniques sere to adapt general dielectric and magnetic anisotropic media. Perfect matching is achieed both by the former, based on a straight generalization of Berenger's PML using a D and B formulation, and by the latter using an E and H formulation. In this paper, a general theory enclosing both formulations is proposed. 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28:414 416, 2001.
