Near-field optical transmittance of metal particle chain waveguides.

A self-consistent model based on the classical fieldsusceptibilities formalism has been developed to simulate recent experiments where metallic particle chain waveguides are addressed locally by the tip of a Scanning Near-Field Optical Microscope (SNOM) [1]. This approach which accounts for the actual optical response of the particles leads to a reliable description of both near-field transmittances and losses of this kind of integrated devices.
