Simulation of Cherenkov Radiation in Magnetized Plasma by a Charged Particle

The theoretical study and simulation of Cherenkov radiation of a charged particle which moves uniformly in magnetized plasma are carried out. The analytical expression of radiated field, eigenvalue, and radiated conditions are obtained. Numerical calculations of the eigenvalues and contour map of radiated field are presented. It is found that the cyclotron frequency and plasma frequency affect the distribution of the eigenvalue. Then the PIC-simulation is applied to analyze the characteristics of this radiation. The results show that the amplitude of confinement magnetic field influences the radiation angle and the amplitude of radiation field. And the wakefield is found in the simulation.
