Abstract

The recently proposed general material-independent perfectly matched layer (GMIPML) and extended perfectly matched layer (EPML) techniques serve to adapt general dielectric and magnetic anisotropic media. Perfect matching is achieved both by the former, based on a straight generalization of Berenger's PML using a equation image and equation image formulation, and by the latter using an equation image and equation image 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.
