信息化视角的电磁场论实验教学研究

Experimental Teaching Research of the Theory of Electromagnetic Field from Information-based Perspective

电磁场实验教学是电磁场论教学的重要组成部分,信息化技术为电磁场实验教学提供了良好的技术手段。采用高斯脉冲作为激励源,与地质雷达电磁探测技术相结合,研究了电磁场在地下介质传播的时间和空间特征,开展电磁场传播实验,从信息化视角展现电磁波在地下介质的传播动态,使抽象的电磁波传播过程变得直观、易于理解,推进电磁场论实验教学发展。

Experiment teaching is an important part of electromagnetic field teaching, and the information technology provides a good technical means for electromagnetic field experimental teaching. This paper uses Gaussian pulse as the excitation source, studies the time and space characteristics of the electromagnetic field propagation in the underground medium based on the ground penetrating radar electromagnetic detection technology. Then the electromagnetic field propagation experiment is developed The propagation of the electromagnetic wave in the underground medium is shown with the information perspective. As a result, the electromagnetic wave propagation process becomes visualized,intelligible, and the study promotes the development of experimental teaching of electromagnetic field theory.
