The Electromagnetic Waves on the Boundary Between Composite with the Metallic 1D-Inclusions and the Environment

The frequency dependencies for the dielectric function of composite which has low content of the randomly-oriented metallic nanocylinders have been studied in the work. The frequencies of the surface plasmonic resonance as a function of the volume content of the metallic fraction have been obtained. The frequency dependencies for the wavenumber of plasmon-polaritons, which propagate on the boundary between mentioned composite and air have been calculated. The existence of the band gaps, in which the surface electromagnetic waves can not propagate, and the existence of the splitting of the frequencies of the surface plasmonic resonance in the case when the electron relaxation in metal can be ignored, have been demonstrated.
