V. Lozhechko, Yu. V. Shestopalov] We consider direct and inverse diffraction problems for a class of domains with noncompact boundaries that arise in mathematical models of the wave scattering by planar screens with arbitrary finite inhomogeneities. We prove the unique solvability of the direct problems in the Sobolev spaces. The inverse problems are formulated and uniqueness of reconstructing the permittivity and the shape of the scatterer from the scattering data is proved. Copyright 2003, Walter de Gruyter Lozhechko V.
