Negative permittivity in Fe–Si–Ni/epoxy magnetic composite materials at high-frequency

The radio frequency permittivity and permeability spectra of Fe–Si–Ni/epoxy magnetic composite materials were investigated in detail. A relaxation frequency dispersion of permittivity has been observed for the composites below percolation threshold, and tunable negative permittivity due to the plasm...
