Theory of Spatially Growing Plasma Waves

Abstract

The linearized theory of spatially growing waves in a uniform plasma is investigated in detail. By solving the dispersion relation in this case, characteristics of excited waves are presented. Behaviors of the growth-rate and the phase-velocity of amplified wave are examined in connection with the frequency and various conditions of the medium plasma and the directed beam. It is seen that the theory is in good agreement with some features of experimental results.
