摘要
编制了一种数值计算程序，计算了同轴异型波导的截止频率与场分布，此方法较等效电路法更适用，与场匹配法的计算结果相吻合，但仅需假定系统中是ＴＥ模就可求得所有参数，计算出场分布并反映出简并情况。制作模型进行了冷测，二者符合良好。计算了阴极尺寸对谐振频率的影响。
A numerical simulation program has been made and the cut-off frequency and field distribution Of coaxial special waveguide are calculated. This method is superior to equivalent circuit method and agrees with the results of field matching method. All parameters can be obtained if provide that the mode of this system is TE mode. The cold testing of this system is done and the results are good agreement on the numerical results. The influence of cathode dimensions on resonant freguency is Calculated as well.
