摘要：
In this paper, we consider the scattering problem by a locally perturbed half-plane, which can be reformulated as an exterior obstacle problem. However, the new obstacle is a bounded domain with nonsmooth boundary. By using the generalization of Green's theorem to nonsmooth domain, we obtain that the obstacle is uniquely determined by the far field pattern. (C) 2004 Elsevier Ltd. All rights reserved.
