Thin layered element method (TLM) is an efficient way for computation of Green’s functions. However, it requires unbounded domain represented by an absorbing boundary or layer. A perfectly matched layer (PML) is one of the highest accuracy techniques to absorb outgoing waves from a bounded domain. In this paper, I apply the PML to the TLM in order to improve calculation precision of elastic wave field in a layered half-space. The accuracy of this method is examined by comparing its results with theoretical solution. It is found that the PML gives good results when compared to conventional method.
