有界电磁波绘制浅探

THE PLOT OF BOUNDED ELECTROMAGNETIC WAVE

有界电磁波在《电磁学理论》和《电动力学》中占有重要地位，但由于有界电磁波的方程是以复杂的函数式分量表示的，其物理意义抽象而不易理解。本文利用ＭａｔＬａｂ算法语言，结合有界电磁波的场方程的函数表达式，以矩形有界空间为例，直观地绘制了有界电磁波在各个层面的电场分布，便于加深对有界电磁波分布的理解。

Bounded electromagnetic wave in the syntonic box and the wave-guide has the most important position. But to understand it is difficult for us. This paper makes use of MATLAB to draw the plot of bounded electromagnetic wave. The plot can make us see its distribution more visually and make us understand it better.
