matlab代码，根据非线性薛定谔方程来模拟光纤内各种非线性效应（克尔效应、四波混频、受激拉曼散射、载流子吸收等）产生超连续谱

Nonlinear optical properties of stimulated Brillouin scattering (SBS) to signal detection in water are analyzed. With the threshold characteristics, SBS only occurs when the high power laser is focused in the SBS cell. When there is an object present in front of the focus, it leads to lower incident intensity and then SBS does not occur. The backward SBS signal depends on the focusing location. The nonlinear optical properties of SBS process in the focusing regime are analyzed theoretically. Wit

By the 90 deg. elastic light scattering investigation and far field observation in the range of 20-800 centigrade, the relation between behavior of light scattering anomalies and evolution of nanodomain structures in lattice of barium sodium niobate (Ba2NaNb5O15, BSN) crystal was clarified. The correlation between anomalies on the temperature curves of the elastic light scattering intensity and temperature transformations of nanodomains was studied by X-ray and electron microscope methods.

针对MIMO非线性系统的模型预测控制（MPC），建立了一种新型的带有外部输入的反向传播自回归（BP-ARX）组合模型，可以得到输入与输出之间的稳态关系。 BP神经网络代表稳态关系，ARX模型代表非线性系统输入和输出之间的线性动态关系。 BP-ARX模型是一个全局模型，可以离线识别，而ARX模型的参数根据BP神经网络和操作数据进行在线缩放。 采用顺序二次规划在线求解二次目标函数，并定义了移位系数以约束递归最小二乘算法的生效时间。 因此，提出了一种参数变化非线性MPC（PVNMPC）算法，该算法可快速响应系统设定点的大变化，并在系统输出接近设定点时显示出良好的动态性能。 在多变量搅拌罐和多变量pH中和过程中的仿真结果说明了该方法的适用性，并对PVNMPC和多变量递归广义预测控制器之间的控制效果进行了比较。

A theoretical model of a nonlinear hyperbolic metamaterial is presented in the form of a stack of subwavelength layers of linear plasmonic and nonlinear dielectric materials. A broad picture of the properties of evanescent waves (high-k modes) in this stack is investigated by plotting global transmi

The identification of nonlinear spatiotemporal dynamical systems given by partial differential equations has attracted a lot of attention in the past decades. Several methods, such as searching principle-based algorithms, partially linear kernel methods, and coupled lattice methods, have been developed to address the identification problems. However, most existing methods have some restrictions on sampling processes in that the sampling intervals should usually be very small and uniformly distri

Locating multiple optimal solutions of nonlinear equation systems based on multiobjective optimization

The dynamics of nonlinear processes in quantum dot (QD) semiconductor optical amplifiers (SOAs) are investigated. Using small-signal measurements, the suitabilities of cross-gain and cross-phase modulation as well as four wave mixing (FWM) for wavelength conversion are examined. The cross-gain modul
