摘要
介绍了用德国CST(Computer Simulation Technology)公司提供的微波工作室MWS (Microwave Studio)4.2软件模拟计算螺旋线慢波系统的色散特性和耦合阻抗的理论方法。通过对矩形夹持杆支撑螺旋慢波结构的模拟计算,与测试结果相比色散特性的平均模拟误差为1.5%左右,耦合阻抗的平均误差为 0.3%左右;相比于 MAFIA仿真,计算精度更高,计算时间更短。
With the Microwave Studio4.2 software provided by the German Computer Simulation Company, the basis method of simulating the dispersion characteristics and interaction impedance for helical slow-wave circuit is described. The simulation for a helical slow-wave circuit supported by three rectangular rods is done with the Microwave Studio4.2. Compared with the measured results, the average error of dispersion simulation result reaches less than 1.5%, and that of impedance less than 0.3%. Compared with MAFIA, CST Microwave Studio4.2 has high simulation accuracy and short simulation time.
