Abstract
The paper considers processes of the electromagnetic radiation propagation at the frequency of 9.027 GHz (corresponding to the wavelength in vacuum of 33.2 mm) in the round-section waveguides of an experimental unit to determine the burning rate of the mixed energy-condensed systems under the high pressure conditions. Qualitative theoretical analysis of the electromagnetic radiation interaction with single metal and contrast dielectric particles in the carrier dielectric medium of a condensed system and arrays of metal and contrast dielectric particles distributed in space was carried out. The paper evaluates the influence of electromagnetic radiation, base material and filler particles on parameters of the resulting standing wave in the microwave unit waveguide for measuring the burning rate of an energy-condensed system, and assesses theoretically the qualitative effect of the filler content on the error in the microwave measurement system. Results of the experimental study of combustion of two model energy-condensed systems, as well as the exemplary model dielectric material (transformer oil) by the microwave method, were analyzed. Study results are the practical justification for introducing the microwave method in diagnosing combustion characteristics of the energy-condensed systems containing particles of the metallized filler
