The results show that complex permeability of the composites has a resonancelike-type dispersion. Although (μ′ 0-1) is rather small (about 0.2), μ″ max achieves 0.53-0.78, due to small effective damping coefficient. The composites also exhibit relatively high resonance frequencies f R covering 20-33 GHz, which are proportional to anisotropy fields H a of the barium ferrites. These properties will be beneficial to the design of electromagnetic composites at a desired working frequency. © 2012 Elsevier B.V.
