Abstract

A two-dimensional plasmon waveguide in the form of rows of silver-shell nanorods distributed in a hexagonal lattice is proposed and compared to the solid-silver case. The transport of energy flow due to surface plasmon coupling is investigated using the finite element method for visible range wavelengths. The proposed waveguide is divided into several sections, with each section consisting of ten nanorods. Results show that the waveguide energy flow exhibits long-range propagation (>8μm or more) by using a series connection of each section, which plays the major role in coupling between them.
