Title: High Frequency Even Harmonics Generation in the Plasmas with Electron Fluxes

Abstract

The flux density time evolution of radiation at the even harmonics frequencies of a test wave is found and its link with the evolution of the current density produced by a constant electric field is established. Even harmonics generation is studied in two regimes: that of free accelerated motion which takes place for small time intervals and that of current saturation corresponding to the time moments much larger than the inverse of the electron-ion effective collision frequency when a quasi-stationary electron motion is established. The generation of even harmonics of pump wave in weakly non uniform plasma with electron heat flux is described as well.
