| 摘 要： | 以基于超材料的太赫兹波透射为目的，设计并制作了四种亚波长开环共振（SRR）超材料。采用连续太赫兹波作为入射激光源，实验测量了它们在1.04 ~4.25 THz波段的功率透射属性，并采用CST Studio进行仿真，结果显示这些超材料存在一个位于2.52 THz的全局透射峰和多个局部透射峰。全局透射峰与SRR阵列的微结构和图形配置等参数有关。为了寻找一个具有较高透射效率的太赫兹感应阵列，比较了四种不同超材料微结构的归一化功率透射性能和感应差别。从这些差别中找到特定图案配置的超材料器件用于太赫兹波感应具有借鉴意义。

| Abstract: | Many fundamental progress and applications of metamaterials in millimeter wave or microwave have been found, but it is still important to design the metamaterials device in the terahertz frequency regime to fill THz-gap in future. Four subwavelength split-ring resonators(SRRs) were designed and fabricated in the terahertz frequency regime, and the transmission properties of four metamaterials was simulated by CST Studio, which can be used to analyze the resonance frequency. The power transmission properties of the devices in the frequency ranging from 1.04 THz to 4.25 THz were investigated by continuous waves terahertz lasers, the measured results revealed a total transmission peak at 2.52 THz and several local transmission peaks. The total transmission peak was related to the microstructures and electronic configurations of specific SRR arrays. In order to find a best SRR array for terahertz sensing with relatively high transmission efficiency, the normalized power transmission performances and sensing differences of four types of metamaterials microstructures were compared. |
