Optical Properties of Metal-Dielectric-Metal (MDM) Nanoantennas
ORAL
Abstract
We present a new design of plasmonic nanoantennas and study their optical properties. The nanoantennas consist of two metal blocks (cuboids or cylinders) stacked vertically with a dielectric spacer. The results from numerical simulations show that such plasmonic nanoantennas exhibit various cavity resonance modes which produce sharp peaks in the near field spectra and leave dips in the far field scattering spectra. Nanofabrication and characterization of these nanoantennas will also be presented in the talk.
