| 摘 要： | 在传播常数随半径变化的情况下近似分析了两模转换条件，得到了模式转换器的初始结构，然后调用迭代法进行优化，最终能得到结构紧凑、带宽较宽、转换效率高的模式转换器。设计了两周期的Ka波段和一周期的W波段TE01-TE02模式转换器，带宽（转换效率95%以上频带宽度）分别达到2.47,8 GHz。CST仿真结果与耦合波仿真程序计算结果吻合较好，验证了该方法的有效性。

| Abstract: | This paper presents a process of designing compact TE01 TE02 mode converters with broadband. Mode conversion condition are approximately derived while propagation constants vary along axis and initial structure of the mode converters is calculated. The initial structure is optimized utilizing iterative method. Two period TE01 TE02 mode converter in Ka band and one period mode converter in W band are designed, and the bandwidths (above 95% conversion efficiency) reach 2.47 GHz and 8 GHz respectively. CST simulation data agree well with those calculated by coupled mode algorithm for both converters. |
