Abstract
Microwave frequency downshift in the time-varying collision plasma has been demonstrated by particle-in-cell simulations. The simulation results are consistent with the theoretical analysis, and the preconditions for microwave frequency downshift are that the collision frequency needs to be greater than the incident wave frequency, and the plasma frequency is two times greater than the incident wave frequency. Finally, the simulation results are compared with the reported experimental results indicating good agreement.
