Frequency features of electromagnetic response of the ferrite containing PETG composites at EHF range

摘要

In the paper results of a research of electrophysical properties of 3D-printed composites based on polyethylene glycol terephthalate and barium ferrite at the of extremely high frequency region (34-258 GHz) are presented. Frequency dependences of composites for a ferrite concentration of 40, 50 and 60 wt .% are given. At a frequency ～ 48 GHz, the region of selective absorption due to ferromagnetic resonance has been experimentally determined. The possibility of using PETG/BaFe_(12)O_(19) composites in the additive technology are assessed.
