"On Mixed Reciprocity Relations in Inverse Scattering"



Abstract:

    Roland Potthast graduated from the University of Goettingen in 1993 and received his PhD in 1994. He is currently employed at the Institute for Numerical and Applied Mathematics, in the same institution, and visited the University of Delaware. His research interests include inverse problems (with emphasis on scattering theory), integral equations and numerical mathematics. He published several papers on these subjects.
    Reciprocity relations are of great importance in the treatment of direct and inverse scattering problems. Mixed reciprocity relations relate the far field pattern of incident point-sources with the scattered field for incident plane waves. In the lecture, we derive mixed reciprocity relations for some acoustic and electromagnetic scattering problems and show their applicability to solve inverse obstacle scattering problems. Questions of uniqueness, stability and reconstruction are investigated.
