Abstract

The effects of SrTiO3 content on the electromagnetic properties and electromagnetic wave absorbing characteristics of SrTiO3-epoxy composites were investigated. As the SrTiO3 content increased, it was found that the complex permittivity and permeability of the composites increased and the resonance frequency moved toward low frequency range. The complex permittivity and permeability of composites were characteristic of the frequency dispersion. The electromagnetic wave absorbing behavior of the composites showed that the center frequency of the attenuation curve was shifted to a lower frequency band with increasing the amount of SrTiO3 and the thickness of composite.
