二维情况下用ＦＤＴＤ方法模拟电磁波的传播情况，没加吸收边界条件，用Ｃ和MATLAB混合编程，信号源是高斯脉冲(Two-dimensional case with the FDTD simulation of electromagnetic wave propagation, no additional absorbing boundary condition, mixed with the C and MATLAB programming, the signal source is a Gaussian pulse)

to make the data at the same length

fdtd 程序源代码（有吸收边界的）给出可是化结果(1D FDTD simulation in free space Without Absorbing Boundary Condition )

说明：  无功功率分离谐波成分和基波成分，采用数学形态学滤波器作为低通滤波(Reactive power components of the separation of harmonic and fundamental components, the use of mathematical morphology filter as a low-pass filter)
