Abstract

In recent years, there has been an improvement in the field of photonics in disordered environments due to its diverse applications in solar collectors, random lasers, catalyst photos and other photonic devices. This work aims to study the phenomenon of light transport in a highly disordered optical medium composed of a colloidal solution of titanium dioxide core-shell nanoparticles coated with a layer of silica (TiO2@Sı́lica) suspended in a solution of ethanol. A program was developed and adapted to carry out simulations using the theory of random matrices, which is executed through the numerical calculation program MATLAB, in addition to the portability of the same program to the Scilab freeware. The program that has a user interface works as a facilitator for the execution and obtaining of data from the simulations performed. The modification carried out in the original program allowed us to vary new parameters, such as the number of channels for the terminals connected to the quantum point studied, this resulted in new results that still need to be studied and better analyzed. keywords: Anderson localization of light.

随着数值模拟的发展，一种新的光学光定位的开始

近年来，无序环境下的光子学在太阳能集热器、随机激光器、催化剂光和其他光子器件等方面的应用有了很大的发展。这项工作旨在研究高度无序的光学介质中的光传输现象，该介质由二氧化钛核壳纳米粒子的胶体溶液组成，该胶体溶液涂有一层悬浮在乙醇溶液中的二氧化硅(TiO2@S)。开发并调整了一个程序来使用随机矩阵理论进行模拟，该程序通过数值计算程序MATLAB执行，并将相同的程序移植到Scilab免费软件中。具有用户界面的程序作为执行和从所执行的模拟中获取数据的促进者。在原程序中进行的修改允许我们改变新的参数，例如所研究的量子点连接的终端的信道数，这导致了新的结果，仍然需要研究和更好的分析。关键词:安德森光定位;光子。核壳。随机矩阵理论。acson@outlook.com.br Revista Física no Campus, v. 1, n. 1, p. 65-79, Campina Grande PB, 2021 Universidade estual da Paraíba http://novo.revista.uepb.edu.br/fisicanocampus Artigo Original
