程序使用一维FDTD模拟真空中TEM波的传播，采用一阶Mur吸收边界，源点强制加源，双向行波，从而是读者很形象的理解FDTD算法！-TEM wave propagation in the vacuum of one-dimensional FDTD simulation program, using the first-order Mur absorbing boundary force plus the source of the source, two-way traveling wave, which is the very image of the reader s understanding of FDTD method.
