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.)

抛物方程能够快速对大区域电波传播特性做出预测，目前已经得到了广泛的应用。压缩包里给出了二维抛物方程的matlab程序(The parabolic equation can quickly predict the propagation characteristics of large region waves. It has been widely used at present. In this paper, a two-dimensional parabolic equation program is given in this paper.)
