1. A lens for manipulating electromagnetic waves comprising:
a substrate;
a first zone on a surface of the substrate, the first zone being configured to manipulate a first wavelength range, wherein the first zone comprises at least one Frustrum cut pyramid structure each having a first set of dimensions that are defined based on the first wavelength range
wherein, the at least one Frustrum cut pyramid structure is positioned within the first zone in a repeating pattern, and a minimum distance between Frustrum cut pyramid structures in the first zone is a minimum wavelength of the first wavelength range; and
a second zone on the surface of the substrate, the second zone being configured to manipulate a second wavelength range distinct from the first wavelength range.
