Annotation: The results of measurements of electromagnetic characteristics of composites are presented: methylmethacrylate (PMMA) + multiwall carbon nanotubes (MWCNT); PMMA + nanopowders of M-, W-, Z- hexaferrite; PMMA + MWCNT+ nanopowders of M-, W-, Z- hexaferrite. The composites containing MWCNT have frequency dependence of dielectric permittivity. Adding of ferrite in nano-powder composites leads to stabilizing of dielectric permittivity. The results can be used for calculation of devices of a microwave range.
