1. A metasurface enabled illumination or sensor array comprising:
at least one illumination source or sensor element;
a plurality of metasurface elements arranged in a planar array such that light emitted from the at least one illumination source or impinging on each of said at least one sensor element passes through the planar array of metasurface elements; and
wherein the plurality of metasurface elements are configured to be asymmetric such that the metasurface elements are configured to imprint at least one of at least two far field functions from the at least one illumination source or direct the light into at least one of the at least two far field functions from the impinging light prior to illumination of the sensor elements based on the light passing through the metasurface elements.
