| 摘 要： | 通过阐述模式识别的重要性及其在高功率微波中的特殊性，论证了利用辐射特性来识别模式的可行性，并以某金属截面圆波导为例，通过纯解析、半解析、数值模拟三种方法对其中的TE11和TM01混合模式辐射场分别进行计算和分析，得到基本物理图像和特征，实验结果为模式判别提供了初步判据。

| Abstract: | This article expounds the importance of mode determination and its particularity in high power microwave. The feasibility of mode determination by radiation characteristics is demonstrated. As an example, the radiation field of mixed TE11 and TM01 mode in a cylindrical waveguide is calculated and analyzed by three different methods to obtain the basic physic figures and the characteristics, which provides the elementary criterion for mode determination. |

| Keywords: | high power microwave waveguide antenna mode discrimination radiation characteristics of multiple modes |
