The relationship between magnetic parameter and microwave absorbing performance evaluation factor of electomagnetic wave absorber such as matching frequency, matching thickness were investigated for Ni-Zn ferrite composites. It was identified that the maximum value of μ_r is shift to low frequency with decrese Ni / Zn ratio and the value of μ_r is maximum in the case of Ni / Zn=1. All Ni-Zn ferrite composites in this study have two matching frequencies in 1-12 ㎓ frequency. It can be suggested that f_(m1) is proportional to resonance frequency and f_(m2) is proportional to the saturation magnetization.
