Abstract

In recent years, more and more attention has been paid on the research and development of terahertz (THz) technologies all over the world. Biosensing in one of the most important applications of THz waves. Metasurface is an artificial two-dimensional material with flexible structures and good electromagnetic wave control capability, which is very suitable for THz wave control and sensing. In this work, a L-shape metasurface THz biosensor was designed, simulated, optimized, micro-fabricated, and finally tested by the time-domain spectroscopy (TDS) system. The simulation and experimental results agree with each other very well. The conclusions show great advantage of metasurface for the THz biosensing application, especially when it is combined with the microfluidic technology in the near future.
