Claim 6:
7. A method of controlling a metasurface to steer light, the method comprising:
receiving light at each of a number of cells arranged on a substrate, each of the cells including at least:
a high-index dielectric block including an interface between a positively-doped material and a negatively-doped material; and
electrodes configured to supply a voltage differential to the cell 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
dynamically altering 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.
