论文摘要
本文着重于电磁波变换的理论分析和模拟，这在教学物理学中广泛遇到。当电磁波与物体的形状不一致时，通常有必要引入电磁波变换以分析两者之间的相互作用。在本文中，我们讨论了三个常见波，即平面波，圆柱波和球形波。我们首先分析它们之间的数学转换方程，然后使用计算机程序绘制仿真图像以直观地显示派生结果。在派生过程中，我们纠正了经典电磁教科书中的错误。最后，通过电磁波转化解决了几个特定的电磁示例。这些例子包括理想的导体缸，球体和理想的介电缸对平面波的散射。模拟结果以图像的形式直观地显示。
This paper focus on the theoretical analysis and simulation of electromagnetic wave transforms, which is widely encountered in teaching physics. When the electromagnetic wave is not consistent with the shape of the object, it is often necessary to introduce electromagnetic wave transforms to analyze the interaction between the two. In this paper, we discuss three common waves, namely plane wave, cylindrical wave and spherical wave. We first analyze the mathematical transformation equations between them, and then use computer programs to draw a simulation image to intuitively show the derivation results. During the derivation, we corrected an error in a classic electromagnetic textbook. Finally, several specific electromagnetic examples are solved by electromagnetic wave transformation. These examples include the scattering of plane waves by ideal conductor cylinder, sphere and ideal dielectric cylinder. The simulation results are displayed intuitively in the form of images.
