Abstract. A comprehensive analysis of the absorption coefficient of polymer composites with nonmagnetic carbon inclusions was carried out depending on their complex dielectric constant, material thickness in the frequency range 26-37 GHz. It has been experimentally established that corrugated composite surfaces lead to a significant increase in the absorption coefficient, and their filler is not the main obstacle to absorption, in terms of the possibility of improving their absorbing properties by changing the direction of the matrix structure and adding various fillers in the manufacture of microwave devices.
Keywords: carbon-based composites, absorber, contact impregnation, liquid surface tension, van der Waals forces, carbon filaments, amplitude-frequency characteristic (AFC), frequency ranges of GHz, elastic modulus, radio absorbing materials (RFM), microwave devices, impregnation under pressure
