摘要

The stretched coordinate (SC) perfectly matched layer (PML) absorbing boundary in cylindrical coordinate system is implemented using the bilinear transform technique. The proposed PML performs much better in attenuating low frequency evanescent waves as compared to the conventional UPML (anisotropic medium). Numerical results show the efficiency of the proposed algorithm.
