Abstract
Embodiments herein are directed to a metamaterial transmission filters including a metamaterial component and a upper medium positioned within proximity of the metamaterial component such that movement of the upper medium changes the resonances and optical transmission, reflection or absorption spectra of the filter. The upper material may be a natural material or a second metamaterial identical or non-identical to the metamaterial component. Embodiments herein are designed to allow both continuous tuning of the optical spectra of the assembly and/or discrete spectral switching.
