摘要
本文提出了一种基于类电磁诱导透明(Electromagnetically Induced Transparency,EIT)效应的太赫兹超材料折射率传感器。该器件结构单元由介质层和金属层构成,金属层是由四开口环和金属条组合的非对称结构。传感器透射谱产生了尖锐的透明峰,实现了类EIT 效应。仿真分析了该器件的传感性能,实现了Q 值为92.0、折射率灵敏度为61.0 GHz/RIU、品质因数(Figure of Merit,FOM)为8.5 的折射率传感功能,远优于对称结构的开口谐振环传感器。这种具有较高Q 值、较高灵敏度和偏振不相关性的太赫兹超材料传感器在无标记的化学、生物传感中具有潜在应用价值。
Abstract
A terahertz metamaterial refractive index sensor based on the electromagnetically induced transparency (EIT) effect is proposed. The structure of the device consists of a dielectric layer and a metal layer, such that the latter is an asymmetric structure composed of four opening rings and a metal strip. The transmission spectrum of the sensor produces a sharp transparent peak, and we realized an EIT-like effect. The sensing performance of the device is analyzed and revealed a Q value of 92, are fractive index sensitivity of 61 GHz/RIU, and a FOM (Figure of merit) value of 8.5. Moreover, there fractive index sensing performance is better than that of the opening split ring resonator sensor, which has asymmetric structure. The proposed terahertz metamaterial sensor has a high Q, high sensitivity, and is polarization-insensitive. This sensor has potential applications in label-free chemical and biological sensing.
