Abstract
A mechanically tunable reflective metamirror optical device for a targeted design optical wavelength includes a dynamically deformable substrate and a sub-wavelength periodic arrangement of patterned isolated gap surface plasmon (GSP) resonators positioned in or on the dynamically deformable substrate. The patterned isolated GSP resonators are movable relative to each other and comprise a patterned optically thin metal layer for the design wavelength, a patterned optically thick metal layer for the design wavelength, and a patterned insulator layer between the patterned optically thin and optically thick metal layers.
