Ferrite-based composites can largely attenuate the energy of incident electromagnetic radiation by reducing the reflection at the interface between the composites and free space. The magnetic and dielectric properties of composites consisting of ferrite fillers and epoxy resin are investigated along with the parameters of microwave absorption. The dependences of the permeability and permittivity in the 1 to 3 GHz range of frequencies are presented.
