摘　　要：利用MAFIA的准周期边界条件对螺旋慢波电路的高频特性进行模拟 ,发现模拟结果在一定的网格取值范围内作微小变化 ,在此基础上使得色散曲线趋于数值收敛 ;并提出利用MAFIA后处理模块直接计算耦合阻抗的方法 ;将模拟计算结果与实验测试值进行比较 ,其平均误差范围达到设计要求 。The high-frequency characteristic of helical slow-wave circuit is simulated by the quasi-periodic boundary condition of the MAFIA.The simulation result represents a little change when mesh points vary in some ranges,so the dispersion curve reaches the numerical convergence.The method of calculating the impedance is put forward using the post-module of the MAFIA.The simulation results are consistent with the experiment data,in which the average error range meets the design precision.It provides some instructional research for the accurate calculation of the software simulation.
