均匀平面电磁波的极化及基于 HFSS极化状态的课堂展示
内容简介：极化是描述电磁波和天线的重要参量之一，是电磁教学中的重要知识点，在卫星广播、雷达、航空航天遥感等领域中有着广泛的应用。介绍电磁波极化这一概念，分析均匀平面电磁波极化的成因，并基于电磁分析软件HFSS（high frequency simulator structure ），呈现了线极化及圆极化波增益图形曲线。课堂中引入仿真图形及数据，增加学生的感性认识及兴趣，使得教学效果得到改善。
Abstract：As one of significant parameters to describe electromagnetic wave and antenna ,polarization is an important knowledge point in electromagnetic teaching .And it is widely used in the fields of satellite radio ,radar ,aerospace remote sensing and etc .Concept of electromagnetic wave polarization is introduced in this paper firstly .Then ,polarization factor of uniform plane electromagnetic wave is analyzed .Based on electromagnetic analysis software HFSS ,gain graph curves of linear polarized waves and circular polarized waves are presented .The introduction of simulation graphics and data in the classroom will increase per-ceptual cognition and interest of students and improve teaching effects .
