中文摘要：

理论和实验研究了一种由开口谐振环（SR）和双金属线（CW）组合的具有类电磁诱导透明（EIT）效应的SR/CW太赫兹谐振器。分别对由单侧开口和双侧开口谐振环的SR/CW谐振器特性进行了仿真，并分析了开口环在结构单元中位置的变化对谐振峰强度和品质因子Q的影响。结果表明，两个谐振器在0.7 THz附近的谐振峰是由开口环LC谐振和双金属线偶极谐振干涉相消引起的。开口环位置变化对单侧开口环的SR/CW结构谐振峰强度和Q值影响较大，而对双侧开口环的SR/CW谐振器的影响很小。利用激光诱导与化学镀铜技术制备了SR/CW谐振器样品，并利用太赫兹时域光谱（THz-TDS）对样品进行了透射性能测试，测试结果与仿真分析基本相符。

英文摘要：

One kind of terahertz resonator consisting of split-ring resonator （SR） and cut wires （CW）, which has electromagnetically induced transparency （EIT）, is studied theoretically and experimentally. The transmission characteristics of the resonators containing one or two gaps for the split ring are numerically simulated, and the impact of the relative position of the split ring on their resonant peaks intensity and Q-factor are analyzed. The resonant peaks of EIT spectra of SR/CW resonators are found around 0.7 THz due to destructive interference between the LC resonance of the split-ring resonator and the dipole resonance of the cut wires. Both the amplitude and Q-factor of the EIT resonance are very sensitive to the position shift of the split ring for the SR/CW resonator with one gap, and are insensitive for the two gaps. Finally, the SR/CW resonators are fabricated on polyimide substrate using laser-induced and chemical non-electrolytic plating with copper, the transmission properties of which characterized by THz time domain spectroscopy are in good agreement with simulations.
