A design of a multiband terahertz (THz) metamaterial biosensor for early cancer detection is proposed. The THz biosensor composed of several arc-shaped connecting parts operates at three different frequencies, and the absorptivity of the three resonant frequencies exceeds 99% in free space. In this work, we analyzed the absorption spectrum and polarization independence under different design parameters, improved the performance of the sensor by adjusting the absorption characteristics of the sensor, and gave the calculation results. Additionally, we studied the influence of the refractive index and thickness of different samples on the sensor, and theoretically calculated the sensitivity of the sensor to basal cells, breast cells, cervical cells, and their corresponding cancer cells. The result shows that the maximum sensitivity of the sensor can reach 642.5 GHz/RIU, which is much higher than the reported biosensors. Therefore, the proposed THz sensor has great potential in early detection and early warning of cancer. (c) 2023 Optica Publishing Group
