一、简介

基于matlab GUI菲涅尔系数计算：通过平面波反射系数演示，解释不儒斯特角，展示垂直极化系数与水平极化系数的幅度和相位关系。

二、源代码

function varargout = Fresnel(varargin)
% FRESNEL MATLAB code for Fresnel.fig
%      FRESNEL, by itself, creates a new FRESNEL or raises the existing
%      singleton*.
%
%      H = FRESNEL returns the handle to a new FRESNEL or the handle to
%      the existing singleton*.
%
%      FRESNEL('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in FRESNEL.M with the given input arguments.
%
%      FRESNEL('Property','Value',...) creates a new FRESNEL or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Fresnel_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Fresnel_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
