LMS Durham Symposium Computational methods for wave propagation in direct scattering Claire Lines (Brunel. UK)A point source method for inverse scattering by rough surfacesAbstractIn this poster we propose a new method for determining the location of an unbounded surface from measurements of scattered electromagnetic waves, based on the point source method of Potthast (IMA J.Appl.Math., 61:199-140, 1998) for inverse scattering by bounded obstacles. We present numerical results for the case of a perfectly conducting surface in TE polarization, in which case a homogeneous Dirichlet condition applies on the boundary and the surface is located as a minimum of the total field. |
