摘　　要：圆波导是重要的微波传输线系统之一,可做成各种用途的波导器件,对其特性的正确理解是对微波工程师和研究者的基本要求。圆波导因涉及到柱坐标系和特殊函数,本科生对此比较陌生,理解起来比较困难。为此,提出一种基于虚拟仿真可视化的辅助教学方法。这种教学方法更重视求解思路和结果的理解,而烦琐的求解过程则交给软件来完成。通过可视化的仿真结果与解析式的对比学习,对圆波导特性的理解变得比较容易,是一种有效的教学方法。The circular waveguide is one of the important microwave transmission line systems,it can be made into various components for various purposes.The correct understanding of circular waveguide theory is the basic requirement for microwave engineers and researchers.However,circular waveguides are more difficult to understand because they involve cylindrical coordinates and special functions.Therefore,a visual assistant teaching method based on virtual simulation is proposed in this paper.This teaching method pays more attention to the understanding of solving ideas and results,while the tedious solving process is completed by software.It is a very effective teaching method to understand the characteristics of circular waveguide more easily by comparing the visual simulation results with the analytical ones.
