说明：  该软件利用Matlab的GUI功能,设计了一个人机交互界面,通过输入相应的参数来计算相应数据,在界面上即时显示相应的矩形和圆波导的场分布图,并可以根据需要进行电场和磁场的单独显示.
(The software uses Matlab' s GUI functions, designed a human-machine interface, by entering the appropriate parameters to calculate the corresponding data, real-time display in the interface of the rectangular and circular waveguide the corresponding field distribution, and can be electric and magnetic fields as needed a separate display.)
