Particle-in-cells Simulation of the Dynamics of Coupled Gyrotrons
Journal of Radio Electronics(2024)
摘要
The problem of mutual synchronization of two coupled gyrotrons in the 170 GHz waveband was simulated using the particle-in-cells method. To reduce the calculation time, an approach based on replacing the asymmetric operating mode with an equivalent axisymmetric mode was used. As a result, the dimension of the problem is reduced, and instead of three-dimensional modeling, 2.5-dimensional modeling can be used. The limiting case is considered when the lowest axisymmetric mode of the circular waveguide TE01 is chosen as the equivalent mode. The results obtained are demonstrated to be in good agreement with the traditional approach based on modeling of averaged equations.
