Evaluation of Characteristics of Electromagnetic Wave Absorbers of Composites Fabricated by Mechanical Milling

Abstract:

Article Preview

It is found through simulation that electromagnetic wave absorbers made of composites of Ni-Zn ferrite and SiO2 particles, which are isolated in a continuous medium of Ni-Zn ferrite, show absorption in the frequency regions both below and above 1 GHz. The measured complex permeabilities are close to simulation values above 1 GHz. Both absorbing bandwidth and center frequency of the composites are close to the desired values expected from the simulation result.
