The boundary conditions for electromagnetic fields are an essential part of electromagnetic field theory teaching,and they are the basis of many subsequent teaching contents.However,the boundary conditions of elec-tromagnetic fields vary in different materials and directions,making it difficult for students to understand and re-member.The finite element method is used to design several stable electromagnetic field and time-harmonic elec-tromagnetic field models,such as charged metal spherical shells,charged dielectric spheres,coaxial transmission lines,metal waveguides,and dielectric planar waveguides.The characteristics of electric and magnetic boundary condi-tions under different situations are demonstrated and discussed,making the teaching content of electromagnetic field boundary conditions richer and more intuitive,which helps students distinguish and understand the characteristics of electric and magnetic boundary conditions under different situations,and improves the teaching quality.
