Abstract

In the present work, I have modeled the P-SV wave propagation in 2D homogeneous and isotropic fullspace and solid half-space using second-order accurate velocity-stress finite difference method (Virieux, 1986). The perfectly matched layer (PML) absorbing boundary conditions (Chew and Liu, 1996) are applied at edges of the computational domain in order to minimize the edge reflections. Stress image method (Graves, 1996) is used to represent the planar freesurface boundary of the half-space. Numerical examples are presented which show excellent absorption of edge reflections with PML boundary conditions.
