Conclusions slow light tuning devices. control and In conclusion, we accomplished the modulation of double PIT impact by integrating monolayer graphene strips and STO film into PIT metamaterials. The simulation benefits show that the two PIT peaks can understand the on-to-off modulation by independently shifting the Fermi amount of strip 1 and strip two. The coupling impact in the PIT metamaterial has been studied utilizing the three-harmonic oscillator model, as well as the theoretical evaluation shows that the recombination impact of the conductive graphene will trigger the changing of dark mode damping, resulting inside the tuning of the PIT peak amplitude. Via the study with the slow light effect of this metamaterial, it was found that two group delays of this metamaterial is usually tuned independently. Furthermore, the frequency choice function on the double PIT transparency window along with the double slow light can also be realized by controlling the temperature in the STO layer. The multi-functional controllable metamaterial realizes theNanomaterials 2021, 11,11 ofamplitude control and frequency choice of PIT transparency windows and delivers a new path for future PIT control and slow light tuning devices.Author Contributions: Conceptualization, T.W. and Y.G.
