摘要
为更好地理解电磁波的反射与折射实验,对实验进行了仿真研究.仿真得到了喇叭天线的近场方向图并分析了利用喇叭天线、金属板和玻璃板验证平面分界面上平面电磁波的反射与折射定律可能存在的误差.针对金属板和玻璃板的尺寸对反射波和折射波的影响进行了分析,模拟了地面、桌面和多设备工作对实验的影响.研究工作可以使教师和学生更好地理解实验中的误差,并加深对实验的认识.
Abstract
To understand the reflection and refraction experiments of electromagnetic waves better,simulation analysis is conducted on this experiment.The near-field pattern of the horn antenna is obtained through simulation,and its influence on the measurement is analyzed.The feasibility and possible errors of verifying the reflected and refracted laws of plane electromagnetic waves at the plane interface using horn antennas,a metal plate and a glass plate are analyzed through simulation.The influence of the sizes of the metal plate and the glass plate on reflected and refracted waves are analyzed,and the effects of ground,tabletop,and multi-devices working simultaneously on the experiment are simulated.Simulation research work can enable teachers and students to better understand the errors in the experiment and have a deeper understanding of it.
