Long-ranging propagation based on resonant coupling effects using a series connection of ten nanoshells in a plasmon waveguide

摘要

A two-dimensional plasmon waveguide in the form of rows of silver-shell nanorods distributed in a hex- agonal lattice is proposed and compared to the solid-silver case. The transport of energy flow due to sur- face 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 often nanorods. Results show that the waveguide energy flow exhibits long-range propagation (>8 (mu)m or more) by using a series connection of each section, which plays the major role in coupling between them.
