“…On the contrary, the dielectric loss factor are found to be increased with methanol content, while both of them are linearly increased with the rise of frequency as a result of increased ionic/molecular rotations. These are seen to be consistence with the results reported in literature [19,30,36]. Furthermore, the electrical properties of the methanol content have also been validated by carrying out extra measurements.…”

“…This proposed structure can be a promising candidate for application of bio sensing and food processing [29]. The metamaterials based on omega shaped resonator have been investigated by other researchers, however their studies are mainly focused on the metamaterial concept [30,31]. In this work, a novel MTM integrated transmission line-based sensor, which operates over wide frequency range of 1-20 GHz and comprises an omega resonator integrated transmission line, is proposed and investigated.…”

In this paper, a new metamaterials-based hypersensitized liquid sensor integrating omega-shaped resonator with microstrip transmission line is proposed. Microwave transmission responses to industrial energy-based liquids are investigated intensively from both numerical and experimental point of view. Simulation results concerning three-dimensional electromagnetic fields have shown that the transmission coefficient of the resonator could be monitored by the magnetic coupling between the transmission line and omega resonator. This sensor structure has been examined by methanol-water and ethanol-water mixtures. Moreover, the designed sensor is demonstrated to be very sensitive for identifying clean and waste transformer oils. A linear response characteristic of shifting the resonance frequency upon the increment of chemical contents/concentrations or changing the oil condition is observed. In addition to the high agreement of transmission coefficients (S21) between simulations and experiments, obvious resonant-frequency shift of transmission spectrum is recognized for typical pure chemical liquids (i.e., PEG 300, isopropyl alcohol, PEG1500, ammonia, and water), giving rise to identify the type and concentration of the chemical liquids. The novelty of the work is to utilize Q factor and minimum value of S21 as sensing agent in the proposed structure, which are seen to be well compatible at different frequencies ranging from 1-20 GHz. This metamaterial integrated transmission line-based sensor is considered to be promising candidate for precise detection of fluidics and for applications in the field of medicine and chemistry.

“…Also, the sensitivity of the proposed sensor is better than those in References 8–10, 12, and 21. Though the sensors illustrated in References 13 and 14 offer better sensitivity, they have achieved such value by compromising with the increase in liquid volume, sensor dimensions, and operating frequency.…”

“…A comparative study among the different features of the proposed microwave liquid sensor and the sensors reported in the literature have been provided in Table 4. It can be observed from the table that the proposed design configuration is greatly minimized compared to the previous structures 8‐10,12‐14 . Also, the sensitivity of the proposed sensor is better than those in References 8–10, 12, and 21.…”

“…However, it exhibits comparatively low sensitivity in the case of other tested samples. An omega‐shaped resonator‐based sensor has been demonstrated in Reference 14 by the same group that improves sensitivity by placing the sensing layer at the back of the substrate. Nonetheless, the sample volume requirement has been also increased for both configurations.…”

In this paper, we have presented a simple, miniaturized, and highly sensitive liquid sensor, which determines the dielectric properties of liquids at microwave frequency. In the proposed design, the concept of interdigital capacitor (IDC) is employed to construct the sensor. The proposed IDC based sensor responds differently depending on the liquids' dielectric property. The proposed structure utilizes the shift in resonance frequency and peak attenuation as the sensing parameter to determine the complex dielectric permittivity of the unknown liquids. The advantage of the proposed sensor structure lies in its compactness (0.08λ 0 × 0.08λ 0 × 0.003λ 0) and high sensitivity, 0.42%. The designed sensor can also be used in the biomedical field for noninvasive bioliquid characterization.

The paper aims to utilize a metamaterial (MTM) structure, specifically the slotted plus‐shapes within a square split‐ring resonator, to analyze the characteristics of the reused oil and also used to classify different oil samples. The proposed MTM structure is designed to operate within the X‐band frequency range of 8–12.4 GHz. The MTM structure is simulated using the high‐frequency EM simulation tool, and the MTM properties are extracted using standard equations. The negative permittivity and permeability characteristics of the proposed MTM structure in the X‐band are studied to verify its suitability for X‐band applications. A sample container is designed to hold the oil samples, and the experiments were carried out using an X‐band waveguide setup with Vector Network Analyzer. The results were analyzed and presented in brief to examine reused oil and classify different oils.
