Abstract In this paper, an electromagnetic metamaterial with single metal layer is proposed and measured based on plasmon-induced transparency effect (PIT). A transmission window with a full width at half maximum (FWHM) 0.17 THz is achieved in 5–8 THz due to the hybridization between bright-bright modes. In this transmission window, the slow-light effect can be found at resonance frequency 6.36THz. Positive group delay and phase delay are obtained by the metamaterial structure. In experiments, this transmission peak is shifted to higher frequency with the radius R increasing, and moved to lower frequency with the lattice period P increasing. Moreover, the transmission peak can be controlled by changing temperature in experiments. This proposed metamaterial shows the the potential for temperature sensing.

基于太赫兹超材料的等离子体诱导透明度的设计和调制

摘要 本文提出并测量了一种基于等离子体诱导透明效应（PIT）的单金属层电磁超材料。由于亮-亮模式之间的混合，在 5-8 THz 中实现了半高全宽 (FWHM) 0.17 THz 的传输窗口。在这个传输窗口中，可以在共振频率 6.36THz 处发现慢光效应。通过超材料结构获得正群延迟和相位延迟。在实验中，该传输峰值随着半径 R 的增加而移至较高频率，并随着晶格周期 P 的增加而移至较低频率。此外，在实验中可以通过改变温度来控制传输峰值。这种提议的超材料显示了温度传感的潜力。
