Abstract
Disorder-induced effects on plasmon coupling in chains of metallic nanoparticles are studied within a dipole model by considering two types of disorder: fluctuations of the particles’ shapes and of their positions. Typical localization effects are found both in the eigenmodes and in the transport behavior of the system, and an estimate of the localization length is made. It is argued that chains with deliberately introduced disorder constitute promising systems for studying localization effects of electromagnetic waves at optical frequencies under well-controllable and manipulable conditions.
