摘　　要：本文在电磁波传播特性理论分析的基础上,结合EastWave构建了均匀平面波在自由空间、理想导体分界面、理想介质分界面、半波长夹层介质和四分之一波长匹配层中传播的虚拟实验教学模型,对其入射、反射和折射进行了虚拟仿真,直观形象化地呈现电磁波传播过程以及遇到边界时电磁波实时动态变化。通过虚拟仿真实验教学验证了电磁传播特性,改善了教学效果,提升了学生理论应用于实践的能力。Based on the propagation characteristics of the electromagnetic waves,a virtual experimental teaching model is designed about uniform plane wave propagating in free space,perfect conductor interface,perfect medium interface,half-wavelength medium layer and quarter-wavelength matching layer in EastWave.The virtual simulations show the propagation process and the real-time dynamic change of electromagnetic wave when it encounters the boundary.Through virtual experiment teaching,the characteristics of electromagnetic propagation are verified,the teaching effect is improved,and the practical ability of students is enhanced.
