dc.description.abstract
An exact nonreflecting boundary condition is derived for the time dependent elastic wave equation in three space dimensions. This condition holds on a spherical surface ${\cal B}$, outside of which the medium is assumed to be linear, homogeneous, isotropic, and source-free. It is local in time, nonlocal on $\cal B$, and involves only first derivatives of the solution. Therefore it can be combined easily with any numerical method in the interior region.
