Excitation of the Transverse Wave with Phase Velocity Lower than the Velocity of Light in an Equilibrium Plasma

Article

The work of external sources uniformly distributed in a homogeneous plasma and exciting in it a circularly polarized wave with phase velocity lower than the velocity of light is analyzed. It is demonstrated that the plasma becomes transparent for the wave in the potential wells of which a sufficiently large number of electrons is trapped. The charged particle shielding effect disappears, and the excited wave amplitude becomes greater than the amplitude of the same wave in vacuum. If the frequency of the external sources approaches the resonant frequency of the wave loaded by the trapped electrons, the wave amplitude increases and reaches a maximum at resonance. The transverse wave excited by the external sources at the resonant frequency is capable to self-propagate in plasma with phase velocity lower than the velocity of light independently of the support by the external sources.
