Summary :

By combining rubber with carbon and ferrite in an appropriate weight ratio, the material which has both dielectric and magnetic losses, suitable for an electromagnetic-wave absorber, is obtained. The dispersion characteristics of complex relative permittivity and permeability of this material are measured, and equations of both permittivity and permeability are derived in RF frequencies. By using these dispersion equations, we can easily simulate applications using this kind of material as an electromagnetic wave absorvber.
