  Plasmonic nanostructures exhibit exotic electromagnetic functions, for example, plasmonic resonance, negative refractive index and enhanced electric field.They can be used in sensors, waveguides, switches, microcavities and plasmonic circuits.Potentially, it can be used to merge electron and photon together in a nano-scale integrated circuits.Many structures have been reported.
