In the article the scheme of the measuring stand of the device model for determining the part of the energy distributed from the generator, the scheme of the measuring stand of the model for measuring the standing water coefficient (VSWR) and the measurement of the transient resistance are presented. The best results are obtained by a partition consisting of two metal plates overlapping the path both above and below the clay layer. So, with a clay humidity of 4%, the total attenuation was 14.4 dB (-6.1 dB without a partition), and at a humidity of 16% -35 dB (-18.4 dB without a partition). There is an increase in attenuation of approximately two times compared to the case without a partition for both dry and wet clay, but the amount of attenuation is insufficient. To increase the attenuation in model 2, two consecutive resonators were created. But the attenuation in this case increased insignificantly in comparison with one resonator. It is obvious that two resonators are upset because of mutual influence on each other. Therefore, it is proposed in a real installation between these two resonators to place a section of a waveguide of nonresonant length with an absorber that will eliminate the coupling between the resonators.
