Quartz Whispering-Gallery-Mode Resonator with Microfluidic Chip as Sensor for Permittivity Measurement of Liquids
Alexey I. Gubin, Irina A. Protsenko, Alexander A. Barannik +3
Studies of biological solutions require high measurement accuracy, the ability to detect low changes in substance concentration, and small amounts of the liquid under test. A micro…
Whispering-Gallery Mode Resonator Technique with Microfluidic Channel for Permittivity Measurement of Liquids
Alexey I. Gubin, Alexander A. Barannik, Nickolay T. Cherpak +4
Studies of biochemical liquids require precise determination of their complex permittivity. We developed a microwave characterization technique on the basis of a high-quality whisp…
Single Whispering-Gallery-Mode Resonator With Microfluidic Chip as a Basis for Multifrequency Microwave Permittivity Measurement of Liquids
Alexey I. Gubin, Irina A. Protsenko, Alexander A. Barannik +2
The accurate measurement of complex liquid permittivity in a frequency range provides important information on liquid properties in comparison to single frequency permittivity inve…

The authors of the article analyze the impact of the global COVID-19 pandemic on the transport and logistics sector. The research is interdisciplinary in nature. The purpose of the…
Microwave Quenching in DC-biased Coplanar Waveguide Based on Thin Film
Nickolay T. Cherpak, Alexey I. Gubin, Alexander A. Lavrinovich +1
In this paper, we report on the results of features in the discovered effect of a strong change in the microwave losses (quenching) in HTS-based coplanar waveguide (CPW) at certain…
DC-assisted microwave quenching of YBa2Cu3O7-δ coplanar waveguide to a highly dissipative state
N. T. Cherpak, A. A. Lavrinovich, A. I. Gubin +1
The paper reports on finding the effect of a strong change in the microwave losses in an HTS-based coplanar waveguide (CPW) at certain values of the input power Pin and direct curr…
Anomalous microwave conductivity coherence peak in c-axis MgB2 thin film
B. B. Jin, T. Dahm, A. I. Gubin +5
The temperature dependence of the real part of the microwave complex conductivity at 17.9 GHz obtained from surface impedance measurements of two c-axis oriented MgB2 thin films re…
DC transport properties and microwave absorption in bulk ceramic sample and film of La_{0.5}Sr_{0.5}CoO_{3-δ}: magnetic inhomogeneity effects
B. I. Belevtsev, N. T. Cherpak, I. N. Chukanova +3
The DC transport properties and microwave absorption (at 41 GHz) are measured in a bulk ceramic sample and a film (220 nm thick) of LaSrCoO. The samples are…
