Figure 1

(a) The artistic impression and (b) SEM image of the Huygens’ metasurface hologram. Silicon nanodisks with different radii are chosen as the building blocks for meta-atoms to realize phase modulation. The nanodisks have the same height of 120 nm and are surrounded by symmetric dielectric environment of glass to enhance transmission efficiency. (c) Phase modulation and (d) transmission of nanodisk arrays with different heights and radii calculated from numerical simulations.
