Calibration and optimization of a metamaterial sensor for hybrid fuel detection

Abstract

Simple, compact, robust and handy device for chemical sensing using microstrip-based metamaterial Complementary-Split-Ring-Resonator (CSRR) is proposed. A pseudo-microfluidic channel is fabricated upon the CSRR pattern to form the sensor. Combination of two liquids namely, ethanol and petrol, and their varying combinations are sensed for hybrid fuel applications. Simulation and experimental results for shifts in resonance frequency and magnitude are discussed. The results of fluidic approach are seen to be repeatable.
