摘要：
We present a microfluidic sensor integrated with metasurface and a terahertz measuring system used for it. To obtain better sensing sensitivity, numerical simulations were conducted to determine the structure and excitation mode for metasurface. A method to obtain the concentration of sample solution was given as an application of the sensor. Asymmetry metasurface are discussed with figure of merit. A new tradeoff index FD is defined to assess the performance of microfluidic sensor and the best metasurface for our microfluidic sensor is selected through FD.
