摘要：
We consider Dirichlet-Neumann problems for two-dimensional wave propagation analysis in piecewise homogeneous media reformulated in terms of boundary integral equations. The related weak problem is based on a space-time energetic formulation recently introduced for single-domain problems. The discretization phase is carried out by means of Galerkin boundary element method. Numerical results obtained with this procedure will be presented and analyzed.
