## Abstract This paper develops a finite element scheme to generate the spatialβ and timeβdependent absorbing boundary conditions for unbounded elasticβwave problems. This scheme first calculates the spatialβ and timeβdependent wave speed over the cosine of the direction angle using the Higdon's on

Two-dimensional sound propagation over an arbitrarily shaped barrier situated on a locally reacting infinite plane in a homogeneous medium is treated using the boundary element method (BEM). The boundary integral equation (BIE) is formulated in terms of a half-space Green's function which is constru
