Optical Plasmonic Yagi-Uda Nano-Antennas Array for Energy Harvesting Applications

2020

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 …

Optical Plasmonic Nano-Antennas Array for Energy Harvesting Applications

2019

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 nanoantenna, an optical analog of the well-established radiofrequency Yagi antenna, stands out by its efficient unidirectional light emission and enhancement. In this paper, an investigation on a novel optical plasmonic nanoantennas array for energy harvesting application is proposed. The study of a novel Yagi nanorectennas array, by optimizing its geometrical parameters, is reported. All the simulations are carried out by using the CST Studio Suite 2018 softwa…

Innovative systems based on optical nanoantennas for energy harvesting application

The purpose of this study is to outline the main guidelines for the design of arrays of optical rectennas aiming to harvest energy and for the optimization of the power transfer to an external load. In particular, the novelty of this study consists in introducing the concept of the integrated design between the array of optical rectennas and the harvesting circuit able to exploit the available energy. The design of the array represents the crucial point in order to optimize the power transfer between the antenna and the load and can influence the rectenna design. On the other hand, the maximum power transfer to the load has to be obtained under matching conditions between the array and the …
