Adaptive visible and short-wave infrared camouflage using a dynamically tunable metasurface.

In this Letter, a dynamically tunable metasurface, which is based on antimony trisulfide, is introduced. In this structure, first a metal-insulator-metal (MIM) nanocavity is optimized in a way that, upon phase change, the visible response switches from a transmissive colored window into a reflective mirror. Later, an indium tin oxide nanoantenna is integrated on the MIM cavity to provide antireflection in the short-wave infrared (SWIR) range for SWIR mode thermal camouflage. The MIM host acts as a thermally tunable substrate to tune the SWIR response of the design.
