Transitional radiation of a modulated electron flux on the sharp border between vacuum and anisotropic plasma

Transitional radiation of a modulated electron flux that moves along a constant magnetic field normally to the sharp plane border of the plasma semispace is considered. Radioemission energy flows to vacuum (s-and p-polarized waves) and plasma (ordinary and extraordinary waves) are calculated. Such a radiation increases near the Cherenkov resonance regime in vacuum (for relativistic electron fluxes) and plasma, and in the case of excitation of quasi-natural modes on the vacuum-plasma border
