Abstract World is rich in unconventional oil and various alternatives to petroleum. However, conventional oil production declines so quickly that it is likely these unconventional oil resources cannot be put into production fast enough, and thus will not be compensated sufficiently. We realize detecting rapid detection of water content in heavy oil. The waveguide consists of a metal-insulator-metal (MIM) waveguide, rectangular cavity resonator, and crescent-shaped cavity resonator. The effects of the coupling distance, geometry of the crescent-shaped cavity resonator and its rotation angle, and length and width of the rectangular cavity resonator on the Fano resonance lines were numerically analyzed. Multiple Fano resonances can be produced as the rotation angle of the crescent-shaped cavity resonator is adjusted, and the sensor’s refractive index sensitivity was found to be \(935.71 \text{n}\text{m}/\text{R}\text{I}\text{U}\). By measuring the water content in heavy oil, we found that the Fano resonance lines shift toward shorter wavelengths as the volume fraction of water content increases. The detection resolution in heavy oil \(1.79\times {10}^{-9}\). The results presented here show that water content in heavy oil can be calculated using the measured change in the Fano resonance wavelength.

The formation of Fano resonance based on graphene heptamers with D6h symmetry and the effect of nanoparticles at different positions on the collective behavior are investigated in this paper. The significances of central nanodisks on the whole structure are studied first by varying the chemical potential. In addition, the effect of six graphene nanodisks placed in the ring on collective behaviors is also investigated. The influence of the nanodisks at different positions of the ring on the Fano resonance spectrum of the whole oligomer is researched by changing the chemical potential and radius. The proposed nanostructures may find broad applications in the fields of chemical and biochemical sensing.

Microwave Losses

One of the conditions for ensuring the safety of air transport operation is the quality of aviation fuel refueled in aircraft. Fuel quality control is a multi-parameter task that includes monitoring the free moisture content. Regulatory documents establish the content of free water no more than 0.0015% by weight. It is developed a direct electrometric microwave resonance method for controlling free moisture in aviation fuels, which consists in changing the shape of the water drops by pressing them on a solid surface inside a cylindrical cavity resonator. This can dramatically increase dielectric losses. Analytical and experimental analysis of the proposed method is carried out. The control range from 0,5 to 30 μl of absolute volume of moisture in aviation fuels with a maximum error of not morethan 25 % is justified. The sensitivity of the proposed method for monitoring microwave losses in free moisture drops transformed into a thin layer by pressing is an order of magnitude greater than the sensitivity of the method for monitoring microwave losses in moisture drops on a solid surface in a resonator. The proposed method can be used as a basis for the development of devices for monitoring the free moisture of aviation fuels in the conditions of the airfield and laboratory. The direction of development of the method is shown.

The One

A simple design of a metallic circular cross-sectional air-filled cavity is presented. Two probes of varied lengths are used to excite TE112-mode wave into the cavity to give a resonant frequency of 5.86 GHz. The experiments show that the resonant frequency of the cavity resonator decreases as the lengths of the probes are increased. The shortest probe in the range of study gives the closest resonant frequency to the one desired.
