A new approach to defining the<strong> </strong>waveguide by the method of complex permittivity (CP) of the substance, based on the results<strong> </strong>of measuring its voltage standing wave ratio in probing the in some frequency range. Considered<strong> </strong>resonator method for determining the CP of liquid petroleum products by placing in the<strong> </strong>pipe cavity measuring cells. The possibility of controlling the quality of coal on the conveyor<strong> </strong>with the use of attenuation of electromagnetic waves passing through the layer under coal is<strong> </strong>study. The results of the research proposed to use for diagnostic and quality control of these<strong> </strong>substances to be transported on a conveyor belt or pipeline wire.</p>}, number={45}, journal={Visnyk NTUU KPI Seriia - Radiotekhnika Radioaparatobuduvannia}, author={Бухаров, С.В. and Овсяніков, В.В.}, year={2011}, month={Jun.}, pages={120-130} }
