Numerical modeling of the process of parametric generation of the cyclotron radiation in a reactive medium

We present the results of numerical modeling of the effect of amplification of coherent bichromatic radiation due to its cyclotron parametric interaction with a modulated ensemble of electrons in the absence of partial synchronism of waves and particles. The numerical results agree with the analytical conclusions. We find that under certain conditions, the developing parametric instability is accompanied by “driving” of the wave frequencies to the resonance with the particles, which results in significant “peaking” of the instability.
