Abstract
The spectral control of thermal radiation is demonstrated using an array of sprit-ring resonators as plasmonic metasurface. Thermally excited plasmonic resonant modes in a meta-atom are found to enhance thermal radiation at specific wavelengths. From numerical simulations, the emissivity at the resonance can be tuned to blackbody level by tuning the coupling between a sprit-ring and a metal substrate. Since the thickness of the metasurface is significantly small compared to the wavelength, these devices are promising candidates for extremely thin film thermal emitters or efficient frequency-converters for wide range of the frequency from infrared to visible.
