摘　　要：阻抗边界是电磁场理论中一个极其重要的概念。以阻抗边界在太赫兹金属波导方面的应用研究为典型案例,介绍了阻抗边界及其简化过程。同时,采用COMSOL软件进行数值计算,将阻抗边界这一抽象概念可视化,并进行直观的展示。最后探讨了阻抗边界的适用范围。Impedance boundary is a crucial concept in electromagnetic field theory.Taking the application of impedance boundary in the field of terahertz metal wire waveguide as an example, we introduce the impedance boundary and its simplification process.Meanwhile, numerical calculations are carried out using COMSOL software to visualise and visualise the abstract concept of impedance boundaries Finally, the applicable range of impedance boundary is discussed.
