Phase-gradient metasurfaces based on local Fabry-Perot resonances
Yanyan cao, Bocheng Yu, Yangyang Fu +2
In this work we present a new mechanism for designing phase-gradient metasurfaces (PGMs) to control an electromagnetic wavefront with high efficiency. Specifically, we design a tra…

Switchable bifunctional metasurfaces: nearly perfect retroreflection and absorption at THz regime
Shan Zhu, Yanyan Cao, Yangyang Fu +4
Here we make use of vanadium dioxide (VO2) to design a bifunctional metasurface working at the same targeted frequency. With the increase of temperature, the functionality of the d…

Enhanced third-harmonic generation induced by nonlinear field resonances in plasmonic-graphene metasurfaces
Yulian Liu, Shan Zhu, Qingjia Zhou +5
Nonlinear metasurfaces offer new paradigm for boosting optical effect beyond limitations of conventional materials. In this work, we present an alternative way to produce pronounce…
