this a 3d fdtd code using matlab and it can be used as a reference for other structures. Dear sir, i need the VIP access please let me have it.

Corrects lightening using a quadratic fit.

Abstract：Noise frequency modulation(FM)jamming。which belongs to blanket jamming。is already become the main form ofnoise jamming at present。because the wideband was gained by it．Tne spectnlnl ofnoise FM jamming is analyzed by time domain autocorrelation method in this paper．It’S jamm g peculiarity and几out— putting signal’S jamming peculiarity ale explained．At last，these time series models ofnoise FM jalllIIling sig— nal and几outputting signal ale built．(Abstract: Noise frequency modulation (FM) jamming. which belongs to blanket jamming. is already becomethe main form ofnoise jamming at present. because the wideband was gained by it.

利用blackman窗设计Ⅳ型数字带通滤波器MATLAB实现代码。(Blackman window design IV digital band-pass filter MATLAB code.)

velocity model of many layers

非线性系统的模型阶次辨识+模型系统辨识，非常有效(Model order nonlinear system identification+ model system identification, is very effective)

形成地球物理地震数据例子，含有3个双曲线有效波，一个水平干扰，一个拟线性的干扰(A geophysical seismic data example, to contain 3 hyperbolic significant wave, a level of interference, a pseudo-linear interference)

说明：  比较好用的watterson模型仿真代码(A better use of Watterson model simulation code)

matlab code for the envelope detector in analog communications.

说明：  仍工智能算法基于粒子群算法的优化程序，用与分类等其他他的地方也有其他的作用等着你们下载哦(atrificial nbnbnbnbnbnbnbnbnnbnbnnbnbnnbnbn)
