1. A meta-lens comprising:
a first region comprising a plurality of first nanostructures that are two-dimensionally provided in a circumferential direction and a radial direction; and
a plurality of second regions surrounding the first region, each of the plurality of second regions comprising a plurality of second nanostructures that are two-dimensionally provided in the circumferential direction and the radial direction,
wherein a geometric arrangement of the plurality of second nanostructures in the plurality of second regions, is different from a geometric arrangement of the plurality of first nanostructures in the first region,
wherein each of the plurality of first nanostructures and the plurality of second nanostructures has a polygonal column shape, and the plurality of first nanostructures and the plurality of second nanostructures are arranged to have a rotational symmetry with respect to the radial direction at a predetermined angle with respect to a rotation axis, and
wherein each nanostructure of the plurality of first nanostructures or the plurality of second nanostructures has a polar coordinate (r, φ), and an interval between adjacent nanostructures of the plurality of first nanostructures or the plurality of second nanostructures is expressed as a function of a distance r in the radial direction and is independent of a rotation angle φ.
