The paper presents the results of a study of composite materials based on the polymer acrylonitrile styrene acrylate (ACA) and filler M-type hexaferrite (BaFe12O19). The results of X-ray diffractometry of hexaferrite powder are presented. The porosity of the obtained composite filament samples was studied. After 9 extrusion cycles, the porosity is reduced to less than 1%. In the EHF range, the transmission coefficient through a sample of a composite material was measured. A sharp decrease in the transmission coefficient is observed in the frequency range from 42 to 55 GHz, which is due to the natural ferromagnetic resonance in BaFe12O19 hexaferrite.
