在分析高斯场与规则波导模式关系的基础上,分别运用数值求解耦合波方程和级连模匹配技术计算了圆波导H11模在不同形状渐变张角喇叭传输过程中与高次模式的耦合过程。在大量计算分析的基础上选择了其中一条曲线加工了实验馈源,利用实验和仿真的结果验证了数值模拟程序的正确性,从实践上确认了利用耦合波理论和模匹配技术设计高功率光滑变张角圆锥高斯馈源的可行性,为进一步分析设计实用型高功率高效率馈源打下了基础。

On the basis of analyzing the relationship of Gaussian field and rules waveguide mode,numerical solution of coupled-wave equation and cascade mode matching technique were used to calculate the circular waveguide H11 mode in different shapes gradient angle of the trumpet in the process of transmission with high times the coupling model process.In a large number of calculation,a curve was selected to process experiment feed source.The experiment and the simulation results verify the correctness of the numerical simulation program.The feasibility of using coupled-wave theory and model matching technology to design high-power smooth change taper angle Gaussian feed is confirmed.The design of practical high-power and high-efficiency feed source is provided.
