目的这是马萨诸塞大学洛厄尔分校固态课程中计算机项目的 matlab 解决方案， 2007 年左右。 问题考虑直接和倒数二维矩形 Bravais 晶格的生成，其间距 'a' 平行于 x 轴，'2a' 平行于 y 轴（边 a 和边 2a 的原始单位单元）。 编写一个程序来： 1) 计算距原点给定（输入）距离的直接空间和倒易空间中每个格点的坐标。 2) 计算 Wigner-Seitz 单元和第一布里渊区的角坐标。 3) 确定角点的坐标和从原点到角点、从原点到边缘中心、从边缘中心到第一象限角点的直线方程（高对称方向） Wigner-Seitz细胞和第一个布里渊区。 运行时案例该作业要求将输入距离设置为最近邻距离的三倍。 然后计算： 表1：直接晶格的坐标表 2：倒格的坐标表 3：与 Wigner-Seitz 单元格点对或原点和边缘点相关的线表 4：与第一个布里渊区的点阵点对或原点和边缘点相关的

Distributed optical fiber Brillouin sensors detect the temperature and strain along a fiber according to the local Brillouin frequency shift (BFS), which is usually calculated by the measured Brillouin spectrum using Lorentzian curve fitting. In addition, cross-correlation, principal component analysis, and machine learning methods have been proposed for the more efficient extraction of BFS. However, existing methods only process the Brillouin spectrum individually, ignoring the correlation in t

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

We demonstrate a multiple wavelength Brillouin/erbium fiber laser in a linear cavity configuration. The laser cavity is made up of a fiber loop mirror on one end of the resonator and a virtual mirror generated from the distributed stimulated Brillouin scattering effect on the other end. Due to the weak reflectivity provided by the virtual mirror, self-lasing cavity modes are completely suppressed from the laser cavity. At Brillouin pump and 1480-nm pump powers of 2 and 130 mW, respectively, 11 c
