In this paper, for the first time, an investigation in terms of efficiency of an energy harvester based on a plasmonic nanorectenna array is proposed. The novel proposed mirrored-arrowhead nanoantenna presents a very low impedance value at the resonant frequency which reduces the mismatching between the antenna and rectifier circuit. Simulation results carried out by the CST 2020 Studio show a resistance value equal to 1.1 kohms at about 350 THz and a very wide bandwidth as the equivalent RF rhombic antenna. This study paves the way to nanoantennas for high-efficiency electromagnetic energy harvesting applications overcoming the photovoltaic technology.

Abstract
In this paper, for the first time, an investigation in terms of efficiency of an energy harvester based on a plasmonic nanorectenna array is proposed. The novel proposed mirrored-arrowhead nanoantenna presents a very low impedance value at the resonant frequency which reduces the mismatching between the antenna and rectifier circuit. Simulation results carried out by the CST 2020 Studio show a resistance value equal to 1.1 kohms at about 350 THz and a very wide bandwidth as the equivalent RF rhombic antenna. This study paves the way to nanoantennas for high-efficiency electromagnetic energy harvesting applications overcoming the photovoltaic technology.File | Dimensione | Formato | |
