Abstract

In this letter, we implemented a unique low cost and high throughput nanofabrication method to realize selective emitters based on metasurfaces. We experimentally demonstrated nearly perfect emissivity and narrowband bandwidth operating in mid-infrared region of spectrum. The emissivity is highly controllable over a wide range of spectrum, merely by tailoring the resonance length of the optical scatterers, as confirmed both in experimental and simulation results. The physical mechanism underlying of resonant absorption is discussed. In particular, the effect of breaking symmetry in inducing an absorption peak is experimentally observed and verified by simulation.
