平面电磁波的数值分析与仿真，包含6个模型。

该程序可用来计算二维条件下1Ghz电磁波在圆柱侧面的散射。-the program simulates the scattering of 1GHz electromagnetic wave by the cylindrical object. the program is written for 2D simulation

用时域有限差分法模拟电磁波的传播，代码中设置了不同的边界，可以观察到电磁波在不同边界条件下的传播-the method, named FDTD, can be used for simulating the transmission of the electromagnetic wave
