Abstract: The article is devoted to development of a method of diagnostics of subsurface inhomogeneity of dielectric medium by quasistatic electric fields of resonance microwave probes. Within the limits of this method the information source of mediums characteristic is the impedance of electrically-small antennas located over the mediums surface. The circuit of the decision of an inverse problem is developed for modelling probes (a cut of a two-wire line, edge capacity of the cylindrical capacitor, etc.) within the limits of Born approach on restoration of spatial distribution of a dielectric permittivity.

Key words: quasistatic electric field, medium inhomogeneity, complex dielectric permittivity, electrically-small antennas, inverse problem.
