Microwave Absorption Properties of Ferrite/Rubber Composite Microwave Absorber mixed Ni-Zn ferrite and $Ni_2Y$ ferrite

Ni-Zn 페라이트와 $Ni_2Y$ 페라이트를 혼합한 페라이트/고무복합형 전파흡수체의 전파흡수특성

In this study, the ferrite/rubber composite microwave absorbers mixed Ni-Zn ferrite and $Ni_2Y$ ferroxplana were prepared in order to control matching condion. The variation of the material constants($\dot{\varepsilon}$, $\dot{\mu}$) and microwave absorbing characteristics were investigated with various ferrite mixing ratio. The material constants of ferrite/rubber composite microwave absorber could be controlled by variation ferrite mixing radio. The matching frequency and thickness could be controlled with various ferrite mixing ratio.
