Plasmonic Metasurface Absorber Based on Electro-Optic Substrate for Energy Harvesting
A highly efficient and broad light absorber capable of wide-angle absorption in the visible and near infrared range is presented and numerically investigated for energy harvesting in a simple geometry. According to the calculated results, the proposed device has a peak absorption level of about 99.9...
