The Function of the U-shaped Pattern and Graphene

Caption

Different U-shaped hole pattern on the metasurface create a striped (a) and a focalized (b) beam output. In b) the beam is concentrated to a small area (red spot), in the same way as a magnifying glass focuses light on a specific point. Moreover, by applying a gated voltage (2.2 V) on graphene, the output beam intensity becomes weaker. Graphene function could be compared to the exposure of a camera.
