A chiral metamaterial sensor was developed and tested in this study to determine the quality of motor oils by analyzing reflection coefficient parameters of S-11 and S-22. The study found resonance frequency shifts in clear and dirty motor oil samples, with high sensitivity and quality factor compared to previous studies.
Motor oils have to be changed periodically in a period of 10.000-20.000 km according to the motor types. A chiral metamaterial sensor that operates in X band is developed to determine the quality of motor oils, numerically analyzed and experimentally tested in this study. The proposed design has square and circular shaped resonators that are printed on IS680 substrate. Reflection coefficient parameters of S-11 and S-22 are employed for the verification of sensor. The physical principle behind the structure in this study is based on the degradation of motor oil, which changes dielectric constant and causes resonance frequency shifts. According to S-11 reflection coefficient data, 40 MHz(0 km-10000 km) and 60 MHz(0 km-5000 km) resonant frequency shifts are observed between clear and dirty motor oils samples. These shifts have the values of 30 MHz(0 km-10000 km) and 120 MHz(0 km-5000 km), when we look at S-22. The simulated and experimental study results are complying with each other. The novel side of this study is to have high sensitivity and higher quality factor when it is compared with similar study results. Furthermore, no such studies have been conducted so far in the literature.
