High-Frequency Electrodynamics of Slow-Moving Limited Media Taking into Account the Additional Specular Reflection

Abstract

The paper presents the results of constructing the physical and mathematical model of highfrequency electromagnetic waves propagation in slowly moving media of finite dimensions, which takes into account the phenomena of specular reflection of these waves. The constructed model is based on eqations designed to determine the speed of electromagnetic waves propagation in slowly moving media of finite dimensions, as well as on equations designed to describe these waves. The feature of these equations lies in the fact that they take into account the Fresnel drag coefficient for electromagnetic waves propagation speed, while the speed of the media isn’t constant, it can depend on time and coordinates. An approach to these equations solving has been developed, as well as an approach to modeling the process of electromagnetic waves propagation in slowly moving media of finite dimensions, based on the use of a difference scheme, in which the motion of these media is taken into account using infinitesimal Lorentz transformations in a difference cell. It has been determined that the developed model and approaches can be used to solve problems associated with the construction of transmitting and receiving paths of radio communication systems and information transmission through moving plasma streams, gas clouds, macroscopic plasma clots, as well as in solving problems of aeroacoustics.
