Plasmon–Polariton Surface Waves at the Interface of a Dielectric and a Nanocomposite with Metal Inclusions

摘要

The features of the propagation of the surface waves a plasmon–polariton-type at the interface of a dielectric and a nanocomposite material with spherical metal inclusions have been considered. The analysis has been performed taking into account damping of propagating waves, which results in the complexity of dispersion relations, and taking into account the nanoparticle size. The frequency dependences of the group velocity and the depth of surface wave penetration into each medium have been constructed, and the distributions of energy fluxes in the structure have been obtained.
