description | This article concerns acoustic scattering from two-dimensional
open cavities in the time domain.
A transparent boundary condition is provided to reformulate
the problem as an equivalent initial boundary value problem in the interior
region of the open cavity. The well-posedness, that is, the existence, uniqueness
and stability of the solution to the reduced problem, is proved via a
"Laplace domain" to time domain analysis. Moreover, time domain
boundary integral equations for the reduced problem are established. |
