A recently granted patent (Publication Number: US11927777B2) discloses a metasurface design that includes cells arranged on a substrate, each cell comprising a high-index dielectric block with electrodes to provide a voltage differential. The controller dynamically adjusts the voltage to alter the refractive index of the high-index dielectric blocks, allowing for the controllable steering of light exiting the cell. The dimensions of each cell are designed to enhance the electric field component of light at a specific wavelength, and the cells are doped to have varying positive and negative charge densities to achieve the desired light manipulation.

Furthermore, the patent also describes a method and system for controlling the metasurface to steer light effectively. The method involves dynamically altering the voltage differentials supplied to the electrodes of each cell to control the refractive index of the high-index dielectric blocks. The system comprises at least one cell with electrodes arranged on opposite sides, separated from the high-index dielectric block, and circuitry to supply the voltage differential. This innovative technology opens up possibilities for precise control over light manipulation, offering potential applications in various fields such as optics, telecommunications, and imaging technologies.
