Abstract
An explanation is provided for why the Bruggeman equation is unsuitable for calculating the effective permittivity of a composite material containing a filler with negative permittivity. Formulas have been derived for calculating the effective permittivity of a composite containing spherical nanoparticles of filler with negative permittivity. These formulas can be used in producing composite materials with specified permittivity when metal nanoparticles are used as fillers in composites. The existence of a non-monotonic “resonant” dependence of the effective dielectric permittivity on the concentration of filler nanoparticles is predicted in these cases.
