应用数值求解耦合波方程的方法,分析了馈源入射端的TE₁₁模沿着各种不同形状渐变张角传输的情况下,馈源内各个模式之间的耦合关系及其口面辐射特性的变化.同时为验证理论和程序的正确性,选择了一个模型进行加工实测,测量结果与理论分析具有较好的一致性.以此为基础,经过大量计算,初步得到了一个功率容量为1GW的准高斯馈源设计方案.

The coupling wave theory is utilized to analyze the process of modes coupling in circular tapers feed. The relationships of modes coupling and radiation performance in different geometical form feeds were obtained. Based on the calculations,a prototype feed has been designed and measured. These measurements demonstrate good agreement with computer prediction using coupling-wave theory software. All that make a base for designing a high power circular Gaussian feed.
