Electromagnetic Response of 3D-printing Carbon-containing Matrix Structure at Sub-THz Frequency Range

In this paper the results of a research in the sub- THz range of the electromagnetic response of matrix structures based on a carbon-containing polymer obtained by 3D printing are presented. Frequency dependences of the transmission coefficient, complex permittivities of matrix structures samples at the frequency range 48-258 GHz are shown. A comparative analysis of the electromagnetic characteristics of the matrix structures with a solid material was carried out.
