详细的介绍了FDTD进行数学建模分析的相关数学理论知识。(A detailed description of the FDTD related mathematical theory knowledge of mathematical modeling analysis.)

人工神经网络，分别对不同的步长，训练网络，绘出相应的权值分布图，对于训练好的网络，选择特定的输入向量，得到网络的输出结果(Artificial neural networks are different steps, training network, plotted corresponding weight distribution, for the trained network, a specific input vector to obtain the output network)

FDTD仿真喇叭天线，能观察得到其电场在自由空间随时间的分布情况。(FDTD method is a time domain analysis.Here we first we design a wave-guide and there after we just increase its broad side.Our aim is to this simulation is plotting its electric field response with time and how will it response in outside free space. Here we just take 170 time steps one who can interested in antenna designing they can also plot the radiation pattern of this HORN antenna.Just take the field in the outside the mouth of HORN antenna and there do the simple formula to near filed far field transfer and measure it at your band of antenna.Best of LUCK all of you.)
