Abstract

We propose and demonstrate a multi-peak high-sensitivity refractive index sensor for the terahertz band. The designed sensor is composed of a flexible polyimide substrate and a metal structure array covering the top, which is easy to be processed and convenient to be used. According to different structural changes, we can adjust the resonant frequency of the designed metamaterial sensor. The simulation results show that the sensor has three resonance peaks (0.46, 1.06, and 1.29 THz respectively) in the frequency range of 0.1-1.4 THz, and among them the maximum refractive index sensing sensitivity obtained is 272 GHz/RIU. The proposed metamaterial sensor with such high sensitivity performance has potential application prospects in biomedical sensing and trace substance detection.
