Abstract
The process by which a closely spaced array of metallic nanoparticles can effectively guide light by means of an interparticle slot which is resonant in the dimension transverse to the chain direction is described. Specific geometries related to the material parameters produce a resonance in a waveguide mode existing between rectangular particles, and this has a dramatic impact on the guiding properties. Use of a model for this resonant transfer permits the design of waveguides which can operate with relatively low loss using this new guiding mechanism.
