A novel dual-band plasmon induced transparency (DBPIT) metamateria l in the terahertz regime is proposed in this article.The DBPIT unit cell consists of a Diabolo-like element as the bright mode resonator and a pair of split ring resonators (SRRs) with different sizes locating on the left and right sides o f the Diabolo-like element as the dark mode resonators of the system.The numerical simulation results show that two pron ounced transparency windows are obtained in the transmission spectrum,the transmission amplitude of the transparency windows can be manipulated via adjusting the size of the bright mode resonator.The classical three-oscillator model is employed to elaborate the physical mechanism of the DBPIT behavior and the investigations show that the two focu sed transparency windows are arise from the coupling between the bright and the two dark resonators,respectively.Sp ecifically,The couplings between the bright and dark resonators can be greatly enhanced by the magnetic field enhancement effect enabled by Diabolo-like geometry of the bight resonator,and the improved mode coupling can enhance the transm ission amplitude of the transparency windows greatly.This work may open up new avenues for designing multiple-ba nd functional devices with highly flexible tunability,such as slow light devices,tunable sensors and multi-band selec tive switching devices.
