摘　　要：针对电磁场与电磁波理论知识晦涩难懂的特点,利用MATLAB强大的工程计算功能绘制二维和三维电磁场图形,增加了教学可视化效果,便于学生理解与掌握理论知识。通过对静电场点电荷和电偶极子电场分布的二维图形、以电磁波传播的三维图形的绘制,生动形象地展示了电磁场内部的分布状态和神秘电磁波的传播形态,使理论概念清晰再现,激起了学生对电磁场与电磁波课程的学习兴趣。In view of the obscure characteristics of the electromagnetic field and electromagnetic wave theoretical knowledge,the powerful engineering calculation function of MATLAB is used to draw two-dimensional and three-dimensional electromagnetic field graphics,which increases the visual effect of teaching and facilitates students to understand and master theoretical knowledge.By drawing the two-dimensional pattern of the electrostatic field point charge and dipole electric field distribution and three-dimensional pattern of electromagnetic wave propagation,the distribution state inside the electromagnetic field and the propagation form of mysterious electromagnetic waves are vividly displayed,so that the theoretical concepts are clearly reproduced,and students’interest in the learning of electromagnetic fields and electromagnetic waves is aroused.
