Analysis of Four Channels Slow Wave Systems of Single Staggered Millitron

用场论方法分析四通道单交错Ｍｉｌｌｉｔｒｏｎ慢波电路。推导出色散方程和耦合阻抗；通过数值计算，对多通道和单通道电路的色散特性和耦合阻抗进行了比较。

A new type of millimeter coupled-cavity TWT slow wave system,four channels slow wave systems,are investigated.Using the field method,the dispersive equation and coupled impendance of these systems are successfully carried out.The computing results shown that the frequency bandwith and coupled impendance of one channel in the four channels structure are the same as those of the independent single channel structure.So it can be concluded that the output power of the four channels TWT is the four times as that of the single channel TWT.
