该程序用fortran90编写，时域有限差分（FDTD)中的分裂场方法。解决了斜入射情况下周期结构的电磁散射问题。(FORTRAN90 prepared with the program, finite difference time domain (FDTD) method of splitting the market. Solved the case of oblique incidence of electromagnetic scattering from periodic structure issues.)

说明：  同时求取不同信号的多个时域特征参数，可以随意更换待分析信号(Multiple time domain characteristic parameters of different signals are obtained at the same time.)

高斯正算坐标程序计算高斯投影的正算问题克拉索夫斯基椭球(Gaussian count is calculated coordinates of the Gaussian projection is counting police used batons for dispersing ellipsoid)

可以进行简单的数学运算：加、减、乘、除,sin(),cos(),tan()等，还可以对数字进行取余和开方的运算。但仅限于十进制下，还可以进行数的正、负之间的相互转换，exit表示退出, clear表示初始化，有一个 TextField用于显示传来的计算结果；Server端用于监听连接请求、计算发送过来的两数的和、送回数据结果。(Can perform simple arithmetic: add, subtract, multiply, divide, sin (), cos (), tan (), etc. can also figure to take over and prescribing arithmetic. But only under the metric system can also be used for a number of positive and negative between the conversion, exit, said exit, clear that the initialization, there is a TextField to display the results from the calculation Server client connection requests for eavesdropping, calculated sent the two and the number of returned data.)
