摘要 利用有限差分离散Maxwell方程的方法,数值模拟了正弦波在不同介质中的传播情况,形成的波传播图像再现了实验过程。通过适当改变参数,可以数值模拟实现不同形式的波传播规律,程序简单,方便教学应用。 The propagation of sinusoidal wave was simulated in different media,with finite-difference time-domain method through discreted Maxwell s equations.The simulation results exhibit the wave propagation process.By changing the input parameters appropriately,the computer program can carry out different propagation shapes of wave.The arithmetic is easy to be realized,and convenient in teaching.
