Title: Polariton dispersion in nanocomposite materials

The several optical properties of crystals are modified due to nonlinearity associated with high intensity of the incident radiation. In the present work, the linear and nonlinear optical characterization of the nanocomposite materials are also discussed in detail. We explore the possibilities of nonlinear effects in the optical parameters in nanocomposite materials. New modes on the polaritonic gap where the propagation of electromagnetic wave is forbidden, are obtained due to nonlinearity. The presence of gap mode shows the propagation of electromagnetic radiation which may be exploited in optical communications.
