摘要

The effective refractive index of a kind of granular composite, which consists of granular metallic and magnetic granular inclusions with different radius embedded in a host medium, is theoretically investigated. Simulation results show that for certain volume fractions of these two inclusions, the negative permittivity peak shifts to low frequency and the peak value increases with increasing radius ratio of the magnetic granulae to that of metallic granulae. Peak value of permeability decreases with the radius ratio, and value peak shifts to high frequency with increasing volume fraction of magnetic inclusion. In addition, the possibility of constructing tunable granular composite LHM by using electrorheological and Magetorheological effect also investigated.
