| Abstract: | The perfectly matched layer(PML) was first introduced by Berenger as an absorbing boundary condition for electromagnetic wave propagation.In this article,a method is developed to ex-tend the PML to simulating seismic wave propagation in fluid-saturated porous medium.This non-physical boundary is used at the computational edge of a Forsyte polynomial convolutional differenti-ator(FPCD) algorithm as an absorbing boundary condition to truncate unbounded media.The incor-poration of PML in Biot's equations is gi... |
