 Title: Pseudo-Differential Operators in a Wave Diffraction Problem with Impedance Conditions Authors: Castro, L.P.Kapanadze, D. Keywords: Pseudo-Differential OperatorHelmholtz EquationBoundary-Value ProblemWave DiffractionHankel Function35J0535J2535C1547H5047G30 Issue Date: 2008 Publisher: Institute of Mathematics and Informatics Bulgarian Academy of Sciences Citation: Fractional Calculus and Applied Analysis, Vol. 11, No 1, (2008), 15p-26p Abstract: We consider an impedance boundary-value problem for the Helmholtz equation which models a wave diffraction problem with imperfect conductivity on a strip. Pseudo-differential operators are used to deal with this wave diffraction problem. Therefore, single and double layer potentials allow a reformulation of the problem into a system of integral equations. By using operator theoretical methods, the well-posedness of the problem is obtained for a set of impedance parameters, and in a framework of Bessel potential spaces.
