Description: 光孤子matlab仿真
注意程序里面的脉冲定义，morder=1就是高斯脉冲，高于1就是超高斯形状。
高斯脉冲的时候，Nc这个参数表征的是啁啾给脉冲带宽带来的增加，
比如Nc=2表示由于啁啾使得高斯脉冲的带宽变为没有啁啾时候的两倍，以此类推。
超高斯脉冲的时候这个参数没有相应的意义。-Soliton matlab simulation Note program inside the pulse defined morder = 1 is the Gaussian pulse, higher than a super-Gaussian shape. Gaussian pulse when Nc of this parameter is characterized is brought chirp to the pulse bandwidth increase, instance NC = 2 represents, and so due to the chirp the the Gaussian pulse bandwidth becomes no chirp when twice. Super-Gaussian pulse when this parameter is not appropriate. Platform: |

Description: This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a two-dimensional Cartesian space lattice comprised of uniform square grid cells.
To illustrate the algorithm, a 6-cm-diameter metal cylindrical scatterer in free space is modeled. The source excitation is a Gaussian pulse with a carrier frequency of 5 GHz.
The grid resolution (dx = 3 mm) was chosen to provide 20 samples.
