Infrared metamaterials for emissivity and absorptivity control
We have developed several strategies for modulating the infrared absorptivity and emissivity of metasurfaces via electrical control signal. These employ such approaches as voltage-induced symmetry breaking and period doubling for controlling the coupling between a guided mode of the metasurface and the continuum. We further describe potential applications in encoding and encrypting light, for development of secure tags.
