Electrophysical Characteristics of Polyvinyl Alcohol/Mn–Zn Ferrite–Spinel Magnetic Polymer Composites

Electrophysical properties of polyvinyl alcohol / Mn–Zn ferrite composites are studied in the 0.05–7 GHz range of frequencies. It is found that the concentration of ferrite determines the values of dielectric permittivity and magnetic permeability. It is shown that composites with ferrite fractions...

Beschreibung
Zusammenfassung:	Electrophysical properties of polyvinyl alcohol / Mn–Zn ferrite composites are studied in the 0.05–7 GHz range of frequencies. It is found that the concentration of ferrite determines the values of dielectric permittivity and magnetic permeability. It is shown that composites with ferrite fractions of 0.2 and 0.4 can be used as radar absorbing materials, while those with fractions of 0.6 and 0.8 can be used as radio shielding materials.
