Abstract

Nowadays, the combination of metamaterials and molybdenum disulfide (MoS₂) plays more and more important roles, due to its broad applications in many areas. Here, we propose a novel hybrid structure for terahertz (THz) wave manipulation with the integration of MoS₂ layer and metamaterials consisting of split ring resonators (SRRs) arrays on Si substrate. Compared with the simulation results of single ring resonator and double ring resonators, it is found that the original dual-mode resonance transforms four mode resonance after inserting the inner ring. When the inner ring is rotated, the multi-mode resonance does not change. The resonance intensity decreases and the frequency moves to the low frequency with the red-shift effect, when MoS₂ is added. The hybrid MoS₂-SRRs structure THz modulator has multi-mode resonance, and the interaction between SRRs and MoS₂ is revealed through the analysis of multi-mode resonance.
