New families of radiation boundary operators are proposed for ยฎnite element simulations of wave propagation problems characterized by the scalar wave equation. These operators have the form Bu j1 Cu j ; j 1; 2; . . . ; J ; where B is the Dirichlet, Neumann, or the Robin operator, and C is an appropr
When solving the wave equation in inยฎnite regions using ยฎnite element methods, the domain must be truncated. We investigate the accuracy of time-dependent non-reยฏecting boundary conditions (NRBC) derived in Grote, Keller (1995), when implemented in the ยฎnite element method. The NRBC annihilate the ยฎ
