Actively tunable nonreciprocal thermal emitter with SiC grating and anisotropy InAs film
Under the external magnetic field, a novel design consisting of SiC grating on a magneto-optical InAs film is proposed to realize tunable nonreciprocal thermal radiation. In combination with low-loss dielectric InAs, the electric field distribution of the guided resonance broke the time-reversal sym...

| description | Under the external magnetic field, a novel design consisting of SiC grating on a magneto-optical InAs film is proposed to realize tunable nonreciprocal thermal radiation. In combination with low-loss dielectric InAs, the electric field distribution of the guided resonance broke the time-reversal symmetry and reciprocity. The nonreciprocity demonstrates a blue shift with an increased magnetic field and a perfect emission has been achieved at a low magnetic field of 1 T. The influence of the height, period, and width of gratings as well as the thickness and volume fraction of the SiC film on the performance of nonreciprocal emission are fully examined. Finally, tunable emission with different incident angles is investigated. This work may assist the application of nonreciprocal thermal emitters to convert and store energy within a wide frequency band. |
