Abstract:

This paper presents a novel metamaterial micro-fluidic sensor with two pairs of symmetrical double split-ring resonators (DSRR) compared to state of the art, which exhibits unique high-Q (~653) resonance and a 34% higher S21 magnitude than a single DSRR and allow, for the first time, real-time dual-channel biochemical testing through the design of two micro channels underneath the metamaterial DSRR. Polyimide was chosen as the substrate material and it shows good temperature stability at -200~300 °C, which makes the sensor enabling to work in harsh environment.

Keywords: metamaterial, sensor, micro-fluidics, biochemical sensing, chemical analysis
