We describe a new, efficient approach to the imposition of exact nonreflecting boundary conditions for the scalar wave equation. We compare the performance of our approach with that of existing methods by coupling the boundary conditions to finite-difference schemes. Numerical experiments demonstrat

In this work we show how to combine in the exact nonreยฏecting boundary conditions (NRBC) ยฎrst derived by Grote and Keller, the calculation of the exterior (far-ยฎeld) solution for time-dependent radiation and scattering in an unbounded domain. At each discrete time step, radial modes computed on a sp
