摘要
基于龙格库塔理论,提出了一种计算回旋管谐振腔本征模式的新方法.不同于传统计算方法,新算法只需要通过对含有本征模式谐振频率和Q值,两个变量的目标函数进行最小值优化,就能够确定出回旋管谐振腔本征模式的所有特性.通过实例的具体计算,可以证明新算法的计算效率,相对于传统计算方法有了本质上的提高.
According to Runge-Kutta theory, in this paper we present a new algorithm of calculating the eigenmodes of gyrotron resonators. Different from in the traditional algorithm, all properties of the eigenmodes can be determined by solving the minimum of a function with two variables, namely the resonant frequency and Q factor, in the new algorithm. Through examples of numerical calculation, it is verified that the calculation efficiency of the new algorithm is much higher than the traditional algorithm.
