Arbitrarily Oriented Perfectly Matched Layer in the Frequency Domain

Page 461.

Abstract:

An arbitrarily oriented perfectly matched layer (PML) is introduced by using complex space mapping for more flexible meshing of microwave engineering problems. The PML can be oriented in any direction. The discussion is extended to two-direction PML's for matching the interface between one-direction PML's, and three-direction PML's for two-direction ones. An example having analytical solution is calculated. Numerical results agree with the analytical solution very well within 0.1%.
