Coupling between Localized Surface Plasmons in Metal Nanoparticle Waveguides
This paper studies coupling between localized surface plasmons in metal nanoparticle waveguides of different materials and sizes, and then discusses another nanostructure, nanoshells, that support localized plasmons, and closes with conclusions in a variety of situations.
