A numerical method for the simulation of elastic wave propagation is presented. Some important practical requirements for ยฎnite dierence methods are formulated. To satisfy these requirements, the proposed method is based on two key features. Firstly, the approximate solution is represented as a set

The approach suggested in [l, 21 is applied to the problem of the propagation of a plan longitudinal wave in an elastic medium containing a periodic system of rectangular defects. Explicit analytical representations for the scattering coefficients as well as a refined low-frequency solution are deri
