| 摘要:点电荷的镜像法是“电磁场与电磁波”课程的重要内容。这部分的教学重点通常在于分析镜像法原理和寻找镜像电荷,但是缺乏对镜像电场空间分布的图形描绘。本文用Matlab软件对镜像电场进行仿真,绘制了点电荷镜像法中多种镜像电场的等位面和电力线细节图,对镜像电场进行了可视化。可视化有利于加深学生对镜像法原理、镜像电荷和镜像电场分布的理解。 |
| Abstract:The mirror method of point charge is an important part of the course of electromagnetic field and electromagnetic wave. The focus of this part is usually to understand the principle of mirror method and to find the mirror charges. In this paper, Matlab is used to simulate the mirror electric field and to draw the equipotential surface and the force line of electric field. The image electric field is visualized. The visualization will help students to understand the principle of mirror method, the mirror charges and the mirror electric field. |
