Theoretical and applied physics, radiophysics, chemistry, physical chemistry, gas dynamics, and fluid dynamics;
Radiophysics, at the dawn of its formation, was a branch of physics covering the study and application of electromagnetic oscillations and radio waves, as well as the implementation of methods developed in it in other sciences, such as biology and medicine.
Modern radiophysics has a complex and branched structure that provides technical mastery of the entire spectrum of electromagnetic oscillations it covers, the study of the physical properties of linear and nonlinear systems (environments) and the creation of their adequate computer models, enrichment with new physical ideas and technologies in radio engineering, electronics, computer science.
