摘要：

A metasurface-enhanced aqueous solution sensor based on attenuated total reflection (ATR) in the terahertz (THz) range was investigated theoretically and experimentally. The metasurface consisting of complementary split rings is lithographed directly on the upper surface of the ATR prism, and the metasurface-enhanced ATR sensor shows great advantages in detecting aqueous solution comparing with the sensor based on either the split rings or the conventional ATR. The concentration of sucrose solution from 1 mol/L to 0.03125 mol/L has been measured, and the detection sensitivity of metasurface-enhanced ATR is 4 times higher than that of the conventional ATR. This design has significant advantages in solution sensing and exhibits great potential for ultrasensitive aqueous biosensor applications.
