Complex Permeability in Absorption Materials of Spinel Ferrite

Abstract

To seek high efficiency and wide frequency band of microwave absorber, the requirement of absorber on absorption materials is studied. It is shown that a larger value of permeability (including real and imaginary parts) of absorption material should be obtained so as to design a high quality absorber. A series of Ni ferrites has been studied. First, the effect of Co addition on complex permeability is studied. Second, the effect of fabrication processes of materials on complex permeability is studied. The experiment results show that the Co content and sintering temperature. Russian translations.
