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…

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…
