| 摘 要： | 为了解高频MILO实验中高阶模频频出现的原因并考察其对MILO器件性能的影响，利用二次开发的3维全电磁粒子模拟程序KARAT对C波段MILO器件进行了模拟研究。在存在非对称激励的情况下由束波互作用可直接导致高阶模的产生，发现了可与实验中高阶模现象比拟的高阶模，并对其中频率为4.01 GHz的模式做出判定，认为此模式是由非对称的电子和场在互作用腔中相互作用产生的高阶TM11模，并经同轴线传输转化得来。对于频率为3.67 GHz和4.53 GHz的另两高阶模目前尚不能判断。

| Abstract: | The C band MILO is simulated by the 3-D PIC code KARAT program in order to study the reason of frequent higher order modes in experiment and their influence on the performance of MILO. Higher order modes are caused by wave-beam action under condition of non-symmetry excitation mechanism in simulation, similar to those found in experiment. The mode of 4.01 GHz is identified and concluded as transformed through coaxial- line from the TM11 mode rising in slow-wave cavities. The other two higher order modes of 3.67 GHz and 4.53 GHz could not be concluded now. |
