摘　　要：利用电磁计算软件Opera-3d对耦合腔行波管周期永磁聚焦系统中的横向场进行数值模拟计算,分析其分布规律,探讨了影响横向场幅度变化的主要因素,模拟表明横向场增大时会降低聚焦电子注的静态流通率。The transverse magnetic field of the periodic permanent magnet focusing system of coupled cavity TWTs is analyzed in this paper by using the electromagnetic software Opera-3d. The factors, which influence the transverse magnetic field, were considered. The simulation results show that the electron static transmission will reduce when the transverse magnetic field increases.
