ARTEKHA The study of the interaction of electromagnetic waves with inhomogeneous plasma can significantly improve the existing concepts about the dynamics of waves in highly inhomogeneous and non-stationary dielectric media, and is also of great importance for various practical applications, such as plasma heating, diagnostics and interpretation of experimental data. It is of interest to analyze the possibilities of implementing reflectionless wave passage through wave barriers based on the development of exactly solvable physical and mathematical models. This paper analyzes such a model based on a nonlinear equation that determines the effective dielectric permittivity profile of the plasma depending on the choice of the dimensionless wave vector profile, taking into account the positive profile of the dimensionless plasma density. The propagation of electromagnetic waves for the case of periodic perturbations and for the case of localized inhomogeneities is considered. It is shown that with an appropriate choice of the parameters of the problem, rather complex spatial profiles can be obtained that implement reflectionless propagation of the electromagnetic wave through the inhomogeneous plasma. Key words: wave barriers, inhomogeneous plasma, reflectionless passage of waves, exactly solvable models. DOI: 10.25791/infizik.08.2019.806 Contacts: - Pp. 03-09.
