Light propagation characteristics in metal-dielectric optical nanocables

In this paper we investigate the field propagation characteristic in new type new optical waveguides, made of glasses and noble metals. The proposed waveguide, having nanosize cross-section, supports propagation of modes with unusual propagation properties. The propagation speed, attenuation and field localization of those modes will be present. The proportional reducing of the coaxial scale have been investigated. The results of this demagnification will be discussed. The comparatively low value of losses will be explained.
