Direct and Inverse Electromagnetic Scattering
The direct and inverse time-harmonic electromagnetic scattering from inhomogeneous media is considered. The physical problem of electromagnetic scattering from known objects is mathematically described by volume integral equations. Being able to master the direct problem is an absolute prerequisite to solving the corresponding inverse problem, which is naturally closely connected. When solving inverse scattering problems one tries to retrieve information about the unknown scatterer from the knowledge of incident probing waves and measured scattering data. We especially investigate methods to reconstruct the geometry and the material properties of inhomogeneous media from scattering data. The objects considered in this context axe either isotropic or anisotropic lossy dielectrics. The objects are assumed to be nonmagnetic. The inverse scattering problem can be formulated as a nonlinear optimization problem which is solved by means of iterative optimization schemes. Numerical examples demonstrate the efficiency of the proposed methods.
