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.
