Abstract
An example apparatus includes a lens arrangement. The lens arrangement includes a first substrate having a first metasurface thereon, and a second substrate having a second metasurface thereon. The first and second metasurfaces are stacked and face one another, the first and second metasurfaces being separated from one another by an adhesive that attaches the first and second substrates to one another. Methods of fabricating the lens arrangements also are disclosed.

An apparatus comprising:
- a lens arrangement including a first substrate having a first metasurface thereon, and a second substrate having a second metasurface thereon,
- wherein the first and second metasurfaces are stacked and face one another, the first and second metasurfaces being separated from one another by an adhesive that attaches the first and second substrates to one another.
A method comprising:
- applying adhesive over a surface of a first substrate having a first metasuface thereon;
- attaching the first substrate to a second substrate having a second metasurface thereon such that the first and second metasurfaces are stacked and face one another, the first and second substrates being attached to one another by the adhesive, and the first and second metasurfaces being separated from one another by the adhesive.
