计算电磁学中FDTD（有限时域差分法）三维的算法程序。(FDTD (finite difference time domain method) three-dimensional algorithm program in computational electromagnetics.)

Silicon channel semivector : Applies the semivector modesolver to compute the TE mode of a sub-micron silicon waveguide. Comparison with the full-vector solution demonstrates some of the inaccuracy of the semivector approximation.

抑制载波单边带simulink程序，进行频谱计算研究，分析信号特征。(Sideband suppressed carrier simulink program, Calculation of spectral analysis of the signal characteristics.)

控制理论算法在采用状态反馈对目标进行控制时，往往忽略了时滞的存在。时滞往往存在于真实的系统中，而忽略时滞所设计的控制器在复杂的系统中可能会失效。本算法基于李雅普诺夫稳定性理论，以LMI的方式给出时滞系统的稳定性分析判据。(Time delay is widely existed in many engineering contrl systems whiile in many contrl theory and algothms time delay is ignored. This algorithm is given to analysis the stability of close- loop feedback time delay systems. And classical examples are given to demanstrate the effectiveness of this method.)
