Classification: CPC nan | IPC G

Claim 0:
1. A metasurface comprising:
a number of cells arranged on a substrate, each of the cells including:
a high-index dielectric block including an interface between a positively-doped material and a negatively-doped material; and
electrodes configured to provide a voltage differential across the high-index dielectric block to flow current along a current path that passes through the high-index dielectric block, at least a portion of the current path being substantially parallel to a plane defined by the metasurface; and

a controller that dynamically alters a voltage differential supplied to the electrodes of each of the cells to alter a refractive index of each of the high-index dielectric blocks in order to controllably steer light exiting the cell.
