Abstract

We propose a metallic nanostructure consisting of a nanodisk in a nanocrescent. At the quadrupole plasmon resonance wavelengths of the nanocrescent/nanodisk structures, the local electric field amplitudes at the crescent tips are 15 times higher than those of the single nanocrescents. In addition, t...
