Correction of boundary element analysis to scattering of surface waves in an elastic half-space

In this paper, the problem of surface wave propagating in an elastic half-space media is investigated by boundary element method. The boundary element method is studied to obtain the far-field displacements generated by time-harmonic loads. An elegant treatment for the truncated point on the boundary is provided in which omitted parts of the boundary are substituted by two fictitious boundaries in the end of two sides of boundary by using reciprocity theorems.
