Abstract:
A gold nanoparticles-functionalized-complementary-split-ring-resonator (CSRR) sensor is fabricated and studied for explicit sensing of a hazardous gas, namely, hydrogen sulphide (H2S) using an electrical metamaterial sensor. Concentrations as low as 1 ppm have been detected with 2 MHz of resonance frequency shift from 2.437 GHz and upto 55 MHz for 100 ppm of H2S, with negligible response to oxygen. The high sensitivity of CSRR metamaterial towards dielectric constant of the subjected material, and the selectivity of the gold nanoparticles towards sulfur moieties, together, show superior properties of proposed sensor. Thus, a combined domain of nanotechnolgy and electrical metamaterials is proposed for improved sensing.
