摘要
为了使初学者更能直观理解电磁波在不同介质中的传播过程,该研究通过运用MATLAB图形化编程,对电磁波进入不同的导电介质中的传播过程进行可视化仿真.以 5G Wi-Fi信号采用的电磁波为研究对象,仿真其在距波源足够远的地方进入干燥的混凝土墙体、海水以及不锈钢墙体中的传播过程.此外对更一般的情况的椭圆极化波在一般导体中的传播过程进行了仿真.仿真结果形象反映了不同介质对电磁波传播的影响以及椭圆极化波的本质特征.
Abstract
To enable beginners to intuitively understand the propagation process of electromagnetic waves in different media,this study utilizes MATLAB graphical programming to visually simulate the propagation of electromagnetic waves entering various electrically conductive media.With electromagnetic waves used in 5G Wi-Fi signals as the research object,the simulation explores their propagation through dry concrete walls,seawater,and stainless steel walls at a sufficient distance from the wave source.Additionally,a simulation is conducted for the propagation process of elliptically polarized waves in general conductors under more general conditions.The simulation results vividly reflect the influence of different media on electromagnetic wave propagation and the essential characteristics of elliptically polarized waves.
