Abstract

It is found through simulation that composite electromagnetic wave absorbers made of Ni-Zn ferrite and SiO₂ particles, which are isolated in the continuous medium of Ni-Zn ferrite, show good absorption. In particular, absorbers show absorption in the frequency regions both below and above 1 GHz for the mixing ratio of SiO₂ of 80 mol%. To simulate the complex permeability of the composite materials, we considered some arrangements of SiCh in the Ni-Zn ferrite medium. Measured values of complex permeability are close to simulated ones above 1 GHz.
