Abstract

Abstract

A generalized perfectly matched layer(GPML) in lossless and lossy media is proposed. The GPML is derived from the Maxwell’s equations in stretched coordinates and can be easily used in multiresolution time domain(MRTD). The validation of GPML is analyzed in frequency domain and the reflectances are attained in several conditions. An example is given to test the performance of GPML. The results show that the reflectance of GPML is below -40 dB under certain frequency and becomes smaller when the space step is smaller and GPML is thicker. GPML provides a general absorbing boundary condition for lossless and lossy media using MRTD.
