description

Optical nanoantennas have been of great interest recently due to their ability to support a highly efficient, localized surface plasmon resonance and produce significantly enhanced and highly confined electromagnetic fields. The Yagi-Uda nanoantenna, an optical analogue of the well-established radiofrequency Yagi-Uda antenna, stands out by its efficient unidirectional light emission and enhancement. In this paper, the design of an optical plasmonic Yagi-Uda nanoantenna for energy harvesting application is proposed. The enhancement of the directivity is reached by means of an organization in array. The simulation results, carried out by 3D code CST Studio, show that the proposed nanoantenna arranged in a nine-nanoantenna array configuration provides good performance in terms of directivity.
