摘　　要：本文结合Matlab和Fortran语言编程,基于有限差分法计算电场强度模拟了电磁波在自由空间、导电媒质、理想导体和理想介质中的传播特点,进行了可视化动态模拟开发,把场和波的抽象概念变为清晰直观的图像和动画,可以使学生形象地理解场和波在不同媒质中的分布和传播特点。The dynamic visualization approach of electromagnetic wave is proposed and implemented by computing the electric field intensity based on the FDTD method, and using mixed programming in Matlab and Fortran. The characteristics of electromagnetic wave propagate in free space, conducting medium, perfect conductor and perfect dielectric medium are modeled. The abstract concept of electric field and electromagnetic wave are developed to the clear and intuitive figure and animation. This can make students understand the distribution and propagation char- acteristics of electric field and electromagnetic wave graphically.
