Near-field inverse scattering problems in noninvasive diagnostics of subsurface dielectric structures

Abstract

A review and last results in the region of subsurface near-field electromagnetic diagnostics of dielectric inhomogeneities are presented. Methods of nondestructive testing of 3D distributed and solid targets (computer tomography and holography, respectively) as well as methods to retrieve the subsurface profiles of onedimensional inhomogeneities in various media are considered.
