工程教育认证背景下电磁实验教学改革

Electromagnetic Experimental Teaching Based on Engineering Education Accreditation

基于现代有限元仿真工具,有效的展示了电磁场实验教学直观性强的优点,提升了学生的学习兴趣和工程实践能力。

Engineering Education Accreditation requires that they can select appropriate engineering tools,use information technology and scientific methods to study engineering problems.Theory of Electromagnetic Fields content is relatively abstract.Finite Element Method electromagnetic simulation software based on Maxwell and HFSS is introduced in courses.As examples,flat capacitor and electrified parallel double wires are taken based on Maxwell,visual graphic images of E line,U line,B and H line can be simulated.It is easy to compare with the theory and it can strengthen understanding of field. Microstrip patch antenna working at 2. 45 GHz is designed based on HFSS antenna simulation,which can promote the understanding of antenna pattern and scattering coefficient. It demonstrates the advantages of intuitive simulation teaching by analyzing the field parameters and distribution characteristics based on Finite Element Method simulation software,and learning interest and engineering practice ability of students are improved.
