摘　　要：电磁场理论是公认的难教、难学和难用,电磁场实验是学生认识电磁场应用的一个窗口。引入有限元现代仿真工具Maxwell及HFSS,通过图形图像诠释抽象的矢量方程。以高压传输线为例,基于Maxwell仿真接头电场分布;以矩形空气波导传输线为例,基于HFSS分析电磁场的周期性分布。实验以解决电磁场问题为依据,通过理论分析、建模仿真和实际操作形成完善的电磁场实验经历,培养学生利用电磁场理论进行分析和解决问题的能力,提升学习兴趣和工程实践能力。Electromagnetic field theory is difficult to teach,learn,and apply,and experiments are a window for students to understand application of electromagnetic fields.Graphics and images are interpreted based modern finite element simulation Maxwell and HFSS software.Based on Maxwell,taking electric field of high-voltage transmission line joints as an example,simulate the field distribution at the joints;Based on HFSS,taking rectangular air waveguide transmission lines as an example,analyze the periodic distribution of electromagnetic fields.The experiment is based on solving electromagnetic field problems,forming a comprehensive electromagnetic field experimental experience through theoretical analysis,modeling and simulation,and practical operation,cultivating students’ability to analyze and solve problems using electromagnetic field theory,enhancing learning interest and engineering practice ability.
