利用S参数，即S11和S21反演介质的有效介电常数和有效磁导率(Inversion of effective permittivity and permeability of dielectrics using S parameters, i.e. S11 and S21)

说明：  用MACCORMACK方法求解一维LAVAL管亚音速流动(solve one dimensional laval tube with the method in maccormack)

阵元间频率增量按对数增加，发射波束不再按距离周期性出现，发射波束图最大值只有一个。相较于阵元间频率增量固定的传统频率分集阵列，log-FDA能够抗距离相关的干扰，而且发射能量不泄露，具有一定的低截获性能。(FDA with logarithmically increasing frequency offset to achieve a beampattern with a single maximum at the target location. FDA radar with uniform interelement frequency offset, its beampattern exhibits maxima at multiple range values. doe tu the multiple maxima, a number of reflectors located at any of the maxima can interfere the target-return, thus deteriorating SINR.)

质心定位算法实现精度要求低的简单定位，加权质心定位比质心定位定位精度更高一些。(Centroid localization algorithm achieves simple positioning with low accuracy requirement, and weighted centroid localization is more accurate than centroid localization.)

这个程序是通过设置不同的参数来创建一个随机图，可以运行。(This program is to create a random graph for simulation.)

matlab实现人体回波模型创建和短时傅里叶测试(Matlab realization of human echo model and short time Fourier test)

用于ABAQUS软件的子程序，可对金属材料的韧性断裂行为进行精确的计算，并预测其断裂行为。(The subroutine for ABAQUS software can be used to calculate the ductile fracture behavior of metal materials accurately and predict the fracture behavior.)

基于matlab搭载的F16动力学分析程序(F16 dynamic analysis program based on MATLAB)

频率分集阵列发射波束图仿真，发射波束具有距离-角度耦合性，发射波束图最大值周期性出现，周期等于c/Deltaf。另外，提供了仿真所用的参考文献。(Transmit beamforming of frequency diverse array is range-angle dependent and its maximam is periodic occurrence. the period is equal to c/Deltaf. besides, the references are provided.)

说明：  用Fortran语言编写的abaqus，Dflux热源子程序，路径为环形路径(Abaqus, Dflux heat source subroutine written in Fortran language, with a circular path)
