Cherenkov radioemission of electromagnetic waves by the moving point charge in the magnetoactive plasma

摘要

1. Cherenkov radioemission of electromagnetic waves caused by the point charge moving along the external magnetic field in the magnetoactive plasma is calculated using the direct solution of the motion equations of the plasma electrons. 2. The proposed method allows taking into account the nonlinear effects accompanying the Cherenkov radioemission. 3. It is shown that the influence of the excited field on the moving charge results in its deceleration. 4. Cherenkov radioemission can be interpreted as the radioemission of the plasma electrons' current excited by the electric field of the moving charge.
