We show that guiding of optical signals in chains of metal nanoparticles is subject to a surprisingly complex dispersion relation. Retardation causes the dispersion relation to split in two anticrossing branches, as common for polaritons. While huge radiation losses occur above the light line, just below the light line the micron-sized loss lengths are much longer than expected. The anticrossing allows to create highly localized energy distributions in finite arrays that can be tuned via the illumination wavelength. Our results apply to all linear chains of coupled resonant scatterers.

Theory of linear chains of metamaterial/plasmonic particles as subdiffraction optical nanotransmission lines (2006, background): “The use of polylogarithm functions for expressing, in closed form, the dispersion of guided modes along such linear chains has also been proposed in recent contributions [25]-[26].”
