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.
