一种单电子追踪微放电蒙特卡洛模拟计算
A Monte Carlo simulation of single electron tracking calculate multipactor
摘要
Abstract
For the new generation of satellite communication systems,more users,more channels and higher bit rates are the inevitable development trend in the future,and multipactor is an important technical bottleneck limiting the development of high-power space microwave components to higher power capacity.Numerical electromagnetic calculations can track the electron trajectories and internal field interactions more accurately,and the change in the number of secondary electrons over time is used as a criterion for the multipactor breakdown threshold.This paper provides a more simplified two-dimensional calculation model,combined with the secondary electron emission model,which can be used for the rapid calculation of the weak links of microwave components,illustrated by the calculation of a parallel flat plate structure with a very narrow gap as an example,which takes into account the electron emission in the low-energy state,and some computational details are illustrated,and its prediction threshold is compared with other simulation methods,with an error of less than 2dB,which verifies the validity of the method.关键词
