Abstract

The equation of an absorbing layer for time-harmonic elastic waves, based on the perfectly matched layer (PML) concept, is formulated in a manner that is easily implemented in finite element software. In the proposed approach, the layer is viewed as an anisotropic material with continuously varying complex material properties. The effect of the PML parameters on its discrete representation is investigated through dispersion analysis. Guidelines for proper selection of the PML parameters are presented. The formulation, with the parameters selected according to the guidelines proposed, performs well in computation.
