The electrodynamic properties of new functional materials at low temperatures in a wide frequency range are being studied at South Ural State University (SUSU). The work is being carried out within a project supported by the Russian Science Foundation (RSF).
The Russian Science Foundation awarded grant support to Tatiana Zubar, Candidate of Sciences (Physics and Mathematics), junior researcher at the SUSU Crystal Growth Laboratory. Her project, Research of Electrodynamic Parameters of Functional Materials in a Wide Frequency Range at Ultra-Low Temperatures, coincides with the Strategy for Scientific and Technical Development of the Russian Federation in area H6.
Within the strategy, researchers are creating intelligent transport, telecommunications, and international transport and logistics systems, contributing to the connectivity of Russian territories, including the Arctic.
"The aim of our work is to study the electromagnetic parameters of new materials in the microwave range. Most papers on this subject relate mainly to the measurement of mechanical or electrical parameters such as electrical resistance. This project will support the development of measurement methods for electrodynamic parameters in a wide range of frequencies from 10 MHz to 50 GHz at temperatures down to 200 degrees Celsius below zero. The influence of introducing different elements into the crystal lattice of the material on the overall parameters at low temperatures will be investigated," said Tatiana Zubar.
Within the project, researchers will study the frequency dispersion of microwave material parameters of composite materials and the dielectric permittivity of powders and composites in a wide temperature range. Modern methods for measuring magnetic permeability in the microwave range will also be proposed.
The results of this research will be used to create new materials and coatings with unique functional properties.
South Ural State University (SUSU) is a university of digital transformations, where innovative research is conducted in most of the priority fields of science and technology development. In accordance with the strategy of scientific and technological development of the Russian Federation, the university is focused on the development of big scientific interdisciplinary projects in the field of digital industry, materials science, and ecology. In the Year of Science and Technology, it will take part in the competition under the Priority-2030 program. The university acts as a regional project office of the World-class Ural Interregional Research and Education Centre (UIREC).
