A five narrow bands terahertz metamaterial absorber based on metal and Dirac semi-metal for high sensitivity refractive index sensing is designed in this paper. The absorber is a traditional sandwich structure. And the most remarkable difference is that two hybrid materials (metal and Dirac semi-metal) are used in the top layer. The numerical results show five absorption peaks can be achieved at 5.527, 5.759, 7.247, 9.257 and 10.186THz, among which the perfect absorption achieve at 5.759, 7.247 and 10.186THz, respectively. The physical mechanism of the proposed absorber is analyzed qualitatively and quantitatively by electric field distributions and Couple-mode theory. In addition, the sensing application of the proposed absorber is also studied. The sensitivity of the sensing band can reach up to 3.89THz/RIU by computation. Finally, we design a specific application scenario to ensure the accuracy of the absorber in application through calculation. We believe that the absorber we designed will shine brilliantly in the fields of thermal imaging, thermal radiation and photothermal detection.
本文设计了一种基于金属和狄拉克半金属的五窄带太赫兹超材料吸收器,用于高灵敏度折射率传感。该吸收器为传统的三明治结构。最显著的不同之处在于顶层使用了两种混合材料(金属和狄拉克半金属)。数值结果表明,在 5.527、5.759、7.247、9.257 和 10.186THz 处可以实现五个吸收峰,其中在 5.759、7.247 和 10.186THz 处分别实现了完美吸收。通过电场分布和耦合模式理论,定性和定量分析了所提吸收器的物理机理。此外,还研究了所提吸收器的传感应用。通过计算,感应带的灵敏度可达 3.89THz/RIU。最后,我们设计了一个具体的应用场景,通过计算确保吸收器在应用中的准确性。相信我们设计的吸收器将在热成像、热辐射和光热探测领域大放异彩。
