Nonlinear third order optical susceptibilities of metal/dielectric composites containing gold nanoparticles were investigated numerically around the plasmon resonance using the degenerate electron gas model. Influence of the nanoparticle size and intensity of the incident light in the real and imaginary part of the susceptibility, local field factor, absorption spectra, and dispersion curves was analyzed. Results are in agreement with the available data in the literature.
