Abstract

In this paper, the results of the research of electromagnetic characteristics of composite materials based on polyethylene terephthalate glycol and black carbon at the Sub-THz frequency range are presented. The samples of composite materials obtained by the additive technology have been made. The frequency dependencies of complex permittivity at the frequency range from 115 GHz to 258 GHz have been measured. The calculated frequency dependences of the absorption coefficient for composites based on Polyethylene terephthalate glycol and black carbon at concentrations of 10, 15, 20 and 25 wt.% are given. The efficiency of absorption of electromagnetic radiation of 3D-printing black carbon contains materials at sub-THz range is shown.
