Abstract

A high sensitive terahertz metamaterial sensor is realized by electromagnetically induced transparency (EIT) analogue effect. This sensor is composed of a metal a split ring resonator (SRR) and a double bars array structure on a flexible polyimide substrate. The physical mechanism of this sensor has been further discussed. Moreover, the resonant peak exhibits red-shift from 1.26 to 1.14 THz as the concentration of the injected ionic solution changes, which makes it a possible application in liquid sensing in terahertz region.
