摘要
给出了一种实现电磁波与目标相互作用现象可视化的方法。首先用时域有限差分法在数值上模拟电磁波与目标相互作用过程,获取电磁场数据,然后利用MATLAB软件的科学计算可视化功能,将原始数据转换为动态图像。从而能够观察到电磁波传播、穿透、散射和吸收等现象,为直观地了解电磁波与目标相互作用的过程提供了一个有效的手段。
In this paper, an approach is presented for the visualization of the interaction between electromagnetic wave and objects.Firstly, the interaction between electromagnetic fields and objects is simulated by the finite difference time domain (FDTD) method to achieve field information. Then, the raw data are converted to images, and the animation of the electromagnetic wave can be viewed through MATLAB. The phenomena, such as wave propagation, penetration, reflection and absorption by objects, can be observed directly. The demonstrative example indicates that the approach provides an efficient tool to view electr omagnetic phenomena.
