Abstract
We design and simulate a simple plasmonic absorber by employing a three-layer structure comprised of square nanoring array on top of the dielectric subtract followed by a gold reflector. To achieve near perfect absorption, several configurations of the top layer (plasmonic nanoparticle) are proposed, which includes a gold nanoring, horizontally split ring, vertically split ring and quad-split ring, respectively. Simulation results indicate that for some geometries, dual broad absorption bands with absorption efficiencies greater than 99% are obtained, which is highly suitable for solar cell applications.
