Electromagnetic Characteristics of Composites Based on Multiferroics Powders at Microwave Frequencies

The results of researches of polymer composite materials are given in this paper. The fillers of composites were: hexaferrite BaCo0.7Zn1.3Fe16O27; and BaTiO3, CaTiO3, Bi4Ti3O12 were chosen as the ferroelectric components. Results of the researches of complex permittivity and permeability showed that composite of W-hexaferrite BaCo0.7Zn1.3Fe16O27 and CaTiO3 had the best electromagnetic characteristics.
