Light harvesting with metasurfaces: applications to sensors and energy generation

Abstract

Metasurfaces have been receiving increasing interest due to the complex array of radiation controlling properties that are possible with single-layer films. This talk and work will focus on metasurfaces that can provide light filtering according to wavelength, polarization, and other properties of an incident beam, and applied to a variety of sensors. Also, metasurfaces that exhibit light trapping and localization that can be used for energy generation will be described. One last group of metasurfaces will be discussed that display complex dispersion curves that exhibit fast-and slow-light properties that can be used to study the complex electromagnetic phenomena.

MIIM Rectenna with a Meta-lens for Enhanced IR Energy Scavenging at 28.3 THz

“…The performance of a MIIM rectenna can be further enhanced by combining it with a metasurface superstrate. The metasurfaces can be used to focus the incoming infrared and light waves for enhanced energy conversion [18][19][20][21]. The localized surface plasmons can be achieved using metasurfaces in the infrared range [19,22,23] and this too decreases the overall harvester structure as compared to reported large-size array configurations [12,13] for the same purpose.…”
