摘　　要：针对金属矩形波导电磁性质的理论公式过于抽象、不易理解的问题,设计了金属矩形波导电磁性质仿真实验。利用FDTD Solutions软件对金属矩形波导建模和仿真,绘制金属矩形波导中的电场和磁场在不同截面上及电流在波导壁上的分布图。该仿真实验有助于学生直观且深入地理解电磁波在金属矩形波导中的传播特点和传播规律。The analytical formulas of electromagnetic properties in metallic rectangle waveguide are abstract and difficulty to understand. A simulation experiment on electromagnetic properties in metallic waveguide was designed to solve the problem. The metallic waveguide was modeled and simulated using the FDTD Solutions. The electric and magnetic field distributions on different cross sections and the current distributions on the four walls of rectangle waveguide were obtained. The simulation experiment can help the students to understand the propagation law and characteristics of electromagnetic waves in metallic waveguide deeply and intuitively.
