摘要：

The complex permeability dispersions and the microwave absorbing phenemena are investigated in ferrite microwave absorbers. The complex permeability of hexagonal(Y- and Z-type) and spinel(NiZn ferrite and NiZnCo ferrite) ferrites microwave absorbers were measured in 200MHz-16GHz range. The theoretical matching frequencies are determined by plotting the measured complex permeability loci on the impedance matching solution map. One or two impedance matching phenomena are observed in the ferrite absorbers according to their complex permeability loci on the impedance matching solution map. It was discovered that the 1st matching frequency(f(m1)) of the ferrite absorber strongly depends on its spin resonance frequency(f(r2)) and the 2nd matching frequency(f(m2)) is independent of the resonance frequency.
