摘　　要：为帮助学生深刻理解频率选择表面的基本原理及物理意义,提出将电磁场仿真软件HFSS和电路仿真软件ADS应用到频率选择表面的专题教学中,将复杂抽象的电磁理论转化为可视化的图形演示,提高了学生的学习兴趣,进而提升了教学效果。以十字形带阻FSS单元为例,采用HFSS以及ADS软件对十字形带阻FSS单元及其等效电路进行了仿真分析,直观地演示电流分布及传输系数示意图等,探究了金属条长度与等效电感的关系及其对传输系数的影响。这种结合实践的教学方式有效地促进了学生对频率选择表面的理解和掌握,学生们也得到了科研入门培训。In this paper, in order to help students understand the basic principle and physical significance, electromagnetic field simulation software HFSS and circuit simulation software ADS were applied to the teaching of frequency selective surfaces. The complicated and abstract electromagnetic theory is transformed into a visual graphic demonstration, so as to improve students’ learning interest and thus improve the teaching effect. Taking the cross-shaped band-stop FSS unit-cell as an example, HFSS and ADS were used to simulate the cross-shaped band-stop FSS unit-cell and its equivalent circuit model. The diagram of its current distribution and transmission coefficient were clearly demonstrated. The relationship between the length of the metallic strip and the equivalent inductance and its influence on the transmission coefficient were also explored. It has been proveed that the proposed learning method involving practice effectively facilitates students’ understanding and mastering of frequency selective surfaces, and it also provides an initial training of research work.
