Nonreflecting boundary conditions for the time-dependent wave equation

Research output: Contribution to journalArticlepeer-review


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 demonstrate a significant gain in accuracy at no additional cost.
