摘要：

We present ultrathin plasmonic reflectarray metasurfaces for arbitrary shaping of the wave phase front at infrared and optical frequencies. The metasurface building blocks are designed exploiting nanocircuit concepts, offering high controllability and low loss. We present a fast and accurate analytical model to tune the metasurface and achieve large conversion efficiency over a broad angular range and moderately broad bandwidth of operation. We suggest the application of these concepts for light manipulation, trapping and harvesting in solar cells technology.
