Profile characteristics inversion of spherical two-body scattering geometries

An inverse problem of continuous wave electromagnetic scattering is considered. It is assumed that the incident and scattered fields are given everywhere and that the material surface properties satisfy the Leontovich boundary condition. Applying the novel concept of electromagnetic inverse boundary conditions it is shown how the shape and the averaged local surface impedance for spherical two-body scattering geometries can exactly be recovered. An important novel contribution is the introduction of analytic continuation methods in three dimensions.
