摘要
从螺旋波纹波导的一般性耦合波传输方程出发,根据螺旋波纹波导的模式耦合规则给出该波导内返波的耦合波方程和色散方程并分析其色散特性,由此分析螺旋波纹波导返波管的工作机理,并通过耦合波理论计算出本征模式中场的分布情况.
According to the general coupled-wave equations of wave-guide with helical corrugation, Based on rules of mode coupling in helical wave-guide, the coupled equation of the helical wave-guide for backward-wave and the formuale for dispersion are obtained, the dispersion characteristics and the working principles for the gyrotron backwardwave oscillator are analyzed. Based on coupled-wave equations, the field distributions for wave-guide with helical corrugation in eigenmode are also given.
