【光学】基于矩阵法和等效界面法分析光学薄

​1 内容介绍

利用光学传输矩阵法处理物理电磁波通过多层均匀化介质实现实时传播,基于界面与传播矩阵构建,导出传输矩阵,获得反射与透射系数,可直观全面分析了解物理电磁波的传播性质.面向增反膜与DBR(分布式拉格反射镜),通过传输矩阵法与Matlab编程,计算拟合反射率与透射率,以全面展现了物理电磁波传播性质与光学特征.结果表明,基于Matlab编程与传输矩阵方法可有效实现多层均匀化介质的矩阵数学算法,通过反射率与透射率全方位可准确物理电磁波的传播状态.通过实际案例可知,在物理教学中有机结合理论知识与数值仿真,适度扩展研究层面,有利于提高学生的物理应用实践能力.

function varargout = LAMBDA_MAT02(varargin)

% LAMBDA_MAT02 MATLAB code for LAMBDA_MAT02.fig

%      LAMBDA_MAT02, by itself, creates a new LAMBDA_MAT02 or raises the existing

%      singleton*.

%

%      H = LAMBDA_MAT02 returns the handle to a new LAMBDA_MAT02 or the handle to

%      the existing singleton*.

%

%      LAMBDA_MAT02('CALLBACK',hObject,eventData,handles,...) calls the local

%      function named CALLBACK in LAMBDA_MAT02.M with the given input arguments.

%

%      LAMBDA_MAT02('Property','Value',...) creates a new LAMBDA_MAT02 or raises the

%      existing singleton*.  Starting from the left, property value pairs are

%      applied to the GUI before LAMBDA_MAT02_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

%      stop.  All inputs are passed to LAMBDA_MAT02_OpeningFcn via varargin.

%

%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one

%      instance to run (singleton)".
