Abstract
We numerically investigate the Au nano-crescent structure which exhibits >24dB local field enhancement in the near-infrared regime. We reveal that the intra-particle plasmonic coupling between the nanocavity and aperture edge causes the giant enhancement and the matching of near-fields determines the coupling efficiency.
