Abstract

Dual split ring resonator based Metamaterial sensor materials is presented in this paper. This complementary split ring resonator (CSRR) is etched in the ground plane on back of the Microstrip line. Full wave electromagnetic simulation is done to verify the resonance phenomenon. Presented metamaterial sensor shows good result around 6GHz. Simulation results show S21 with -31 dB notch depth at resonant frequency. Electromagnetic properties like effective electric permittivity (varepsilon) and magnetic permeability (μ) of the sensor are derived from S-parameters simulation. Standard photolithography technique is used in fabrication of this metamaterial sensor using low cost FR4 substrate. S-parameters are measured by using Keysight technologies Vector Network Analyzer N5224B. S-parameters simulated and measured results show good agreement. By measurement of only resonant frequency (GHz) and the magnitude (dB) response of the sensor with material under test (MUT) the dielectric constant of the material can be calculated numerically. This nondestructive measurement technique has many applications in material testing for security and bio-sensing.
