We find some useful and effective approximations of the dispersion relation of the fundamental surface plasmon wave propagating around a curved dielectric-metal interface. These estimations are valid even with a very small curvature radius, which is the case of interest for nano-optics applications, and are validated through the numerical solution of the characteristic equation of the curved interface.

Abstract

We find some useful and effective approximations of the dispersion relation of the fundamental surface plasmon wave propagating around a curved dielectric-metal interface. These estimations are valid even with a very small curvature radius, which is the case of interest for nano-optics applications, and are validated through the numerical solution of the characteristic equation of the curved interface.
