Problems of linear time-dependent dispersive waves in an unbounded domain are considered. The infinite domain is truncated via an artificial boundary B, and a high-order non-reflecting boundary condition (NRBC) is imposed on B. Then the problem is solved by a finite difference (FD) scheme in the fin

An exact non-re#ecting boundary condition was derived previously for use with the time-dependent Maxwell equations in three space dimensions. Here it is shown how to combine that boundary condition with the variational formulation for use with the "nite element method. The fundamental theory underly
Non-reflecting boundary conditions are introduced for the two-dimensional Fresnel/SchrΓΆdinger equation. These are nonlocal in time and in space. Time discretization is done by the trapezoidal rule in the interior and by convolution quadrature on the boundary. A convergence estimate is given for the
