摘要
In polymeric medium with random distribution of plasmonic spherical nanoparticles, we find that the real and imaginary parts of the effective permittivity form a circle. Though the effective permittivity depends on the permittivity of the host medium, the fill fraction of guest nanoparticles, the resonance frequency of plasmonic spherical particles and the frequency of incident wave, the center and the radius of the circle are only decided by the permittivity of the host medium and the fill fraction of guest nanoparticles. Numerical computations for different kinds of polymeric media and different fill fractions verify the results.
