摘要
针对"电磁场与电磁波"课程教学中关于"场"与"波"的物理概念抽象,学生理解困难的情况,我们将电磁场专业算法FDTD(时域有限差分)引入课程教学中来。利用算法模拟时变场与物质的相互作用,借助编程处理即可显示电磁波在媒质中的传播特性,有助于学生对于电磁波传播规律的理解与掌握。
In the teaching of ＂Field and Wave Electromagnetics＂,the physical concept on ＂field＂ and ＂wave＂ is abstract, and isdifficult for students to understand. In view of this, FDTD （Finite-Difference Time-Domain） is introduced into the courseteaching. The simulation of the interaction for time-varying fieldand material is easy to implement through the algorithm, and thepropagation characteristics of electromagnetic wave in mediumcan be displayed by programming. It is helpful for students tounderstand and master the law of electromagnetic wave propagation.
