赤外波長領域におけるグラフェンメタサーフェスを用いた熱ふく射制御

抄録

In the present study, we numerically demonstrate wavelength-selective thermal radiation emitter made of graphene-covered Ag grating and it filled with silicon. Underlying physical mechanism is clarified by rigorous coupled-wave analysis. We find that the emission peaks associated with magnetic polariton (MP), whose resonance wavelength can be dynamically tuned by varying graphene chemical potential. This study could facilitate the new tunable thermal radiation sources in the infrared region.
