Simulation Results

Cancer is always the greatest threat to human health. In this work, a split-ring resonator (SRR)-based sensor was simulated for label-free detection on biomarkers in microwave. The model of biosensor was simulated by Computer Simulation Technology 2017 (CST2017) and some influences of feature parameters on resonance frequency and Q-factor were also discussed. From the simulation results, the model of sensor in our work showed ultrahigh Q-factor and sensitivity under different permittivities and also exhibited a trend of better performance when it works in higher frequency. Therefore, the SRR-based biosensor will become an important application in cancer precaution and treatment in the future.

Abstract In this work, we propose a microwave sensor that allows the characterization of dielectric materials based on a differential configuration. A microstrip permittivity sensor of the surrounding material is proposed using a split ring-resonator to measure differentially. The geometry was optimized and was numerically analyzed using CST STUDIO. The numerical analysis of the metamaterial unit cells is carried out first, to determine the operating band. After that, the metamaterial cell was employed to design the differential microstrip permittivity sensor. The obtained results reveal that the proposed sensor has the capability to characterize different materials whose relative dielectric permittivity’s are in the range of 9.8 to 80 with great performance. The device has a total size of 86 mm × 60 mm and operates around 3 GHz. In this band, the sensor reaches a sensibility of 2.89 MHz and a Q-factor of 70.15. Thus, this work shows a compact, reusable, label-free, and non-destructive microwave sensing device and paves the way for high accuracy sensing of the dielectric properties of different materials due to its high- Q-factor as well as high sensitivity.
