Abstract: Metasurfaces have been one of the quickly developed cutting edge research fields with potential important applications. In this paper, our previous research achievements of Pancharatnam-Berry type metasurfaces composed of nanorods were introduced, whose phase modulation presents interesting features. Such metasurface is capable of generating dispersion-less interfactial phase discontinuities and controlling the light propagation. Several functional applications were proposed and demonstrated, including anomalous refraction, dual-polarity metalens, broadband vortex beam generator, helicity-dependent surface plasmon polariton unidirectional excitation and three-dimensional metasurface holography.
