摘要：
Two different compositions with Ba(Ti0.5CO0.5)(2.1)Fe9.9O19 and BA(Ti0.5CO0.5)(3.2)Fe8.8O19 Of Barium ferrite with a magnetoplumbite structure (M-type) had been obtained by the conventional ceramic technology. The complex permeability and permittivity of the materials were measured in the 2-18GHz band. Ba M-type ferrite materials mixed with polyvinyl chloride plasticizer and, frit are pressed to form flakes (180mmx180mmx2mm). of rubber-ferrite. The absorption properties of the single layer rubber-ferrite absorber are measured. by Agilent 8722ES network analyzer (2-18GHz), Compared with the theoretical calculation, it was found that preferable properties of microwave absorption were obtained by using the bank of two ferrite materials singly over a narrow frequency region. Almost all of the samples in the multi-layer rubber-ferrite absorber exhibited a minimum reflection loss less than -10db with the thickness (d(m)) 22mm.
