Abstract: Possibilities of diagnostics of dielectric inhomogeneities in a medium
by data of scattered field measurements above a lens of left-handed
metamaterials are considered. In this paper, a method is developed based on the
solution of inverse scattering problem by multilayer measurements of 2D
distributions of complex amplitudes of electric field with a scanning
source-receiver system. Numerical simulation of 3D structure retrieval of
distributed dielectric inhomogeneities (of tomography) and of the surface shape
retrieval of solid targets (of computer holography).
Key words: noninvasive diagnostics, tomography, holography, inhomogeneities of permittivity, lens of left-handed metamaterials,
inverse scattering problem.
