Abstract
The direct and inverse three-dimensional time-harmonic electromagnetic scattering from inhomogeneous media is considered. Volume integral equations are used to describe mathematically the physical problem of electromagnetic scattering from known objects. 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. This paper deals with methods to reconstruct the geometry and the material properties of inhomogeneous media from scattering data. The objects considered in this context are isotropic lossy dielectries. 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.
