Taming the Blackbody with Infrared Metamaterials as Selective Thermal Emitters

Xianliang Liu, Talmage Tyler, Tatiana Starr, Anthony F. Starr, Nan Marie Jokerst, and Willie J. Padilla

In this Letter we demonstrate, for the first time, selective thermal emitters based on metamaterial perfect absorbers. We experimentally realize a narrow band midinfrared (MIR) thermal emitter. Multiple metamaterial sublattices further permit construction of a dual-band MIR emitter. By performing both emissivity and absorptivity measurements, we find that emissivity and absorptivity agree very well as predicted by Kirchhoff’s law of thermal radiation. Our results directly demonstrate the great flexibility of metamaterials for tailoring blackbody emission.



Infrared Spatial and Frequency Selective Metamaterial with Near-Unity Absorbance

Xianliang Liu, Tatiana Starr, Anthony F. Starr, and Willie J. Padilla

We demonstrate, for the first time, a spatially dependent metamaterial perfect absorber operating in the infrared regime. We achieve an experimental absorption of 97% at a wavelength of 6:0 μm, and our results agree well with numerical full-wave simulations. By using two different metamaterial sublattices we experimentally demonstrate a spatial and frequency varying absorption which may have many relevant applications, including hyperspectral subsampling imaging.
