Electromagnetics good book for develop,good luck(Electromagnetics good book for develop, good luck)

基于matlab的切比雪夫滤波，巴特沃滤波器设计，比较全，很好的源代码( Chebyshev filtering and Buttord filter design baseing on the matlab. more complete, good source code )

说明：  对萨德系统AN/TPY-2雷达的威力范围进行仿真计算。原创！！(The power range of SAD AN/TPY-2 radar is simulated. Original!!)

用计算流体力学方法模拟粒子碰撞，可以自定义各种参数包括粒子数，粒子密度，半径等。 可用于重力坐标系或者无重力空间。

应用背景该算法可以应用与辨识的领域，主要针对一系列输出误差系统的辨识，并且效果显著，辨识是现在学术界都在研究的一项很重要的技术，关系到很多领域，有十分重要的价值。关键技术该程序的算法主要基本依据为最小二乘法，由于最小二乘法只能解决线性问题，不能解决输出误差系统的辨识，因此本算法基于辅助模型建立的最想二乘法，来辨识输出误差系统。

Linear Prediction Coefficient Computation

以matlab为工具利用BP网络实现数据的建模和预测。(Matlab as a tool to use BP network for data modeling and forecasting.)

计算成组滑动的滑窗检测器的最佳门限已知: 击中数N = 128, 组宽n = 8，PF = 10¡ 6，PD = 90 假设以下条件: (a) 信号不起伏 (b) 忽略天线波束调制 1 (c) 计算PD时忽略目标区以外噪声的影响 组门限(第二门限)为K=8 滑窗的门限(第三门限)为L=16 (滑窗中包含的组数为16) 求解: 最佳的KOPT 和LOPT，对这题做了具体仿真实现。需要的朋友，一定知道很有用。(Optimal threshold calculated as group slidable window detector is known: hit number N = 128, the group width n = 8, PF = 106, PD = 90 assuming the following conditions: (a) signal is not undulation ( b) ignore the antenna beam modulation 1 (c) the calculation of PD ignored outside the target area noise of impact group door limit (the second door limit) for K = 8 sliding window of the door limit (third door limit) for L = 16 (sliding window contains group 16) to solve: the best of the KOPT the LOPT, these questions do specific simulation to achieve. A friend in need, we must know to be useful.)

this gives you detailed abt the active power filter and its used. You can mitigates the harmonics by using a active power filter.

In order to reproduce Figure 3 in the Replica Paper, do the following in order: 1. Run "Linear_test.m" 2. Run "Lasso_Optimal Regularization.m" 3. Run part 0,1 and 2 (not part 3) from "Lasso_test.m" 4. Run "Zero Norm Regularization_Optimal Regularization.m"
