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…
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…
Coherent perfect absorption and laser modes in a cylindrical structure of conjugate metamaterials
Yangyang Fu, Yadong Xu, Huanyang Chen +1
In this work, we theoretically find that coherent perfect absorption (CPA) and laser modes can be realized in a two-dimensional cylindrical structure composed of conjugate metamate…
