Engineering Education Accreditation requires that they can select appropriate engineering tools ,useinformation technology and scientific methods to study engineering problems.Theory of Electromagnetic Fieldscontent is relatively abstract.Finite Element Method electromagnetic simulation software based on Maxwell andHFSS is introduced in courses.As examples ,flat capacitor and electrified parallel double wires are taken basedon Maxwell,visual graphic images of E line ,U line ,B and H line can be simulated.lt is easy to compare withthe theory and it can strengthen understanding of field. Microstrip patch antenna working at 2.45 CHz isdesigned based on HFSS antenna simulation, which can promote the understanding of antenna pattern andscattering coefficient,lt demonstrates the advantages of intuitive simulation teaching by analyzing the fieldparameters and distribution characteristics based on Finite Element Method simulation software , and learninginterest and engineering practice ability of students are improved.
