A Highly Efficient Plasmonic Lens Based on a Single Annular Ring With Cross Section of an Asymmetric Slot
A simplified plasmonic lens composed of a single concentric annular ring with cross section of an asymmetric slot is proposed and investigated. By adding an auxiliary nanocavity under the primary annular slot, unidirectional plasmonic waves are efficiently launched to the inward direction and focuse...
