In this paper, a high-performance terahertz sensor is proposed. The sensor obtains a perfect narrow-band transmission spectrum at 3.842 THz with a Q value of 137 at the resonance frequency. The sensitivity reaches 160 GHz/RIU at the thickness of the substance to be measured of 10 μm, with good sensing performance. The results show that it has a promising application in terahertz high-sensitivity biosensing detection.
