摘要
为了加强学生对导波模式的理解,提高教学质量,利用有限差分法分析了平板介质波导中的模场分布,并将计算结果可视化.将电磁场与电磁波中的抽象的公式化结论转化成图像视觉描述,不仅可以丰富教学内容,而且可以帮助学生直观地分析与理解抽象的概念和规律,从而提高课程的教学效果.
In order to enhance the students’understanding of guided-wave mode and improve the teaching quality,Finite Difference Method is used to analyze the mode field distribution in planar dielectric waveguide,and the calculation results are visualized.Transforming the abstract formulaic conclusion of electromagnetic field and electromagnetic wave into image visual description can not only enrich the teaching content,but also help students analyze and understand the abstract concepts and laws intuitively,so as to improve the teaching effect of the course.
