1. A meta-lens comprising: a first region including a plurality of first nanostructures that are two-dimensionally arranged in a circumferential direction and a radial direction based on a center point, wherein a positional arrangement of the plurality of first nanostructures is determined according to a first rule; and
a plurality of second regions surrounding the first region and including a plurality of second nanostructures that are two-dimensionally arranged in the circumferential direction and the radial direction based on the center point, wherein a positional arrangement of the plurality of second nanostructures is determined according to a second rule,
wherein each of the first rule and the second rule has parameters w and p, w denoting a width of each of the plurality of first nanostructures or the plurality of second nanostructures and p denoting an arrangement interval in the circumferential direction between the plurality of first nanostructures or the plurality of second nanostructures,
wherein a region, in which a section satisfying Δw×Δp>0 and a section satisfying Δw×Δp<0 are included, is formed and extends in the radial direction in the first region and any one of the plurality of second regions,
wherein when an arrangement interval in the circumferential direction of a plurality of nanostructures positioned at a first radius r1 is p1 and an arrangement interval in the circumferential direction between a plurality of nanostructures positioned at a second radius r2 adjacent to the first radius r1 in a direction away from the center point in the radial direction is p2, one of the following two conditions is satisfied:
r2−r1=(p1+p2)/2 or r2−r1={(p1+p2)/2}∧(3/2);
wherein the section satisfying Δw×Δp<0 indicates that a change in w and a change in p for adjacent nanostructures of the plurality of first nanostructures or the plurality of second nanostructures is inversely proportional; and
wherein the section satisfying Δw×Δp>0 indicates that the change in w and the change in p for adjacent nanostructures of the plurality of first nanostructures or the plurality of second nanostructures is directly proportional.
