Experimental observation of anomalous optical transmission in interlaced metallic wire meshes
Weijie Dong, Xiaoxi Zhou, Xinyang Pan +4
In conventional plasmonic media and plasmonic metamaterials, such as metallic wire mesh, longitudinal mode of electromagnetic wave manifests itself in frequency overlapping transve…
Gauge invariance in phase-gradient metagratings
Qingjia zhou, Lei Gao, Yadong Xu
Phase gradient metagratings/metasurfaces (PGMs) have provided a new paradigm for light manipulations. In this work, we will show the existence of gauge invariance in PGMs, i.e., th…
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…
Controllably asymmetric beam splitting via gap-induced diffraction channel transition in dual-layer binary metagratings
Yangyang Fu, Jiaqi Tao, Ailing Song +2
In this work, we designed and studied a feasible dual-layer binary metagrating, which can realize controllable asymmetric transmission and beam splitting with nearly perfect perfor…
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…
