In this study, we have developed an efficient metamaterial (MTM)-based portable fuel oil sensor in order to distinguish branded and unbranded fuel-oil samples. Electromagnetic properties of the fuel-oil samples are experimentallyobtained and these data are defined in numerical analysis to design and test the performance of MTM sensor. Then, simulated MTM-based sensor structure is fabricated and measured to observe the efficiency and agreement to numerical results. Numerical and experimental studies are conducted in the microwave frequencies of 10–11 GHz. The experiment results are in accordance with the simulation ones. It can be seen from the results that the proposed MTM-based sensor can be implemented into the sensor industry for distinguishing the branded and unbranded fuel oil for several frequency regions.

In this study, asymmetric transmission, natural chirality phenomena and a retrieval study with chiral metamaterials (MTMs) are numerically and experimentally focussed, investigated and discussed by examining the polarization conversion effect. Suggested multi-functional designs have simple geometries ($\pi$-shaped), low losses and huge optical activities. In addition, these new designs are numerically and experimentally retrieved in the study. The proposed model has many advantages with respect to the asymmetric transmission and chiral MTM studies in the literature. These advantages arehaving simple geometries ($\pi$-shaped), large asymmetric transmissions, small chirality like natural materials and also hug chirality can also be provided by rotating one of the resonators. Besides, the proposed structure can be easily reconfigured for other frequency regimes to provide new chiral MTMs or can be adopted for different application areas from defence systems to stealth technology which will be examined in our future studies.
