The results of experimental measurements in the frequency range 10 kHz – 1 GHz of the complex dielectric permittivity of quartz granule powders of various sizes moistened with distilled water and a salt solution are presented. On the basis of these results, a relaxation model has been constructed that makes it possible to separate the influence of relaxation processes caused by polarization of the...
A generalized multi-relaxation refractive mixing dielectric model of moist soils is suggested for frequencies in the range from 0.2 to 14.8 GHz. The model is based on dielectric measurements in this frequency range at a temperature of 20°С for relative moisture content (by weight) changing from 2 to 43%. The model expands the range of applicability of the single-relaxation model suggested previously...
In this paper, the results of measurements in the frequency range from 10 MHz to 1.0 GHz of the complex dielectric permittivity for some moist artificial soil, that is, mixtures consisting of quartz sand and bentonite clay components, with varying particle-size distributions, are discussed. The measurements were conducted with the use of coaxial line and capacitor probes in conjunction with a vector...
