Analysis reveals characteristics of plasmon-polariton waves in metal nanorods and dielectric waveguides, highlighting their electric field distributions.
The article presents the results of solutions of dispersion equations of plasmon-polariton waves (PPW) propagating in a round metal nanorad and a round dielectric waveguide with a metallic film. The distributions of the dependences of the electric field components Ez on the radial coordinate for these waves are given. A comparative analysis of the characteristics of the existing PPW in the considered electrodynamic structures is presented. The results are obtained taking into account the actual properties of metals in the optical range.
