Abstract
This paper considers an inverse problem for wave propagation in a pert urbed, dissipative half-space. The perturbation is assumed to be compa ctly supported. This paper shows that in dimension three, the perturba tion is uniquely determined by knowledge of the Dirichlet-to-Neumann m ap on an open subset of the boundary.
