Abstract
An apparatus includes a substrate, a first patterned layer, and a second patterned layer. The first patterned layer may be coupled to the substrate and may have a first metasurface pattern. The second patterned layer disposed separately from the substrate and the first patterned layer, and may have a second metasurface pattern. Movement of the first patterned layer relative to the second patterned layer may be controllable via control circuitry such that a gap distance of a gap between the first patterned layer and the second patterned layer is changed to cause a transmittance for radiant energy of a selected wavelength passing through the apparatus to change from a first transmittance value to a second transmittance value.
