Excitation, Propagation, and Focusing of Surface Plasmon Polaritons around A Pair of Subwavelength Holes on Silver Thin FilmY. Oshikane
Osaka University, Osaka, Japan
Simulation results regarding excitation, propagation, and focusing of SPP waves around a pair of subwavelength holes on silver thin film by COMSOL Multiphysics + RF Module are presented. This research has been performed for development of a novel tiny spot of extremely intensified optical near-field at the apex of optical fiber probe for scanning near-field optical microscope.
