片状Fe-Si-Al/Co2Z铁氧体复合组分的微波电磁性能和阻抗匹配特性

he Fe-Si-Al/Co2Z ferrite composites were prepared by balling-milling. The microstructure, microwave electromagnetic properties and impedance matching performanceof the series of composites were discussed. With the content of Fe-Si-Al particles increasing, the complex permittivity and permeability both increase. The calculated reflection losses indicate that the absorption performance of Fe-Si-Al/Co2Z ferrite composites is better than the pure Fe-Si-Al and Co2Z ferrite. Through discussing the impedance matching condition, it can be concluded that a proper weight ratio of the Fe-Si-Al/Co2Z ferrite composite can improve the impedance matching performance of the materials which results in prefect absorption.
