Exact nonreflecting boundary conditions are derived for the time dependent Maxwell equations in three space dimensions. These conditions hold on a spherical surface B, outside of which the medium is assumed to be homogeneous, isotropic, and source-free. They are local in time and nonlocal on B, and

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

An exact nonreflecting boundary condition was derived previously for timedependent elastic waves in three space dimensions [SIAM J. Appl. Math. 60, 803 (2000)]. It is local in time, nonlocal on the artificial boundary, and involves only first derivatives of the displacement. Here it is shown how to
