Abstract. The complex permittivity spectra of mineral medium-clay soil samples from The Krasnodar Territory, Russian Federation, with different moisture content at a temperature of 20℃, were measured in the frequency range of electromagnetic waves from 15 MHz to 50 GHz. An analysis of dielectric relaxations in the studied wet soil was carried out using the method of retrieving the relaxation time distribution function from the measured complex dielectric permittivity spectra. The relaxation time distribution function for the wet mineral soil was found to be discrete with four relaxations. The times and relative contributions of dielectric relaxations to the spectrum of complex permittivity of the mineral soil depending on moisture content were investigated in the frequency range under consideration.
Key words: permittivity, mineral soil, spectroscopy, relaxation time distribution function.
Financing: The work was carried out within the framework of the scientific topic of the State Assignment of the Kirensky Institute of Physics of the Siberian Branch of the Russian Academy of Sciences.
