平面光波在电介质表面的反射特性仿真研究

文中根据麦克斯韦电磁理论,利用电矢量和磁矢量来分析光波在两介质表面的反射特性,把平面光波的入射波、反射波和折射波的电矢量分成两个分量:一个平行于入射角,另一个垂直于入射角,对平面光波在电介质表面的反射和折射进行分析,推导了菲涅尔公式,并结合MATLAB研究光波从光疏介质进入光密介质,以及光波从光密介质进入光疏介质时的反射率、透射率、相位等随入射角度的变换关系。同时对光波在不同介质中传播时的特性变化进行仿真研究,根据仿真结果分析了布鲁斯特角、全反射现象及相位变化的特点。有关各量的平行分量与垂直分量依次用指标p和s来表示,s分量、p分量和传播方向三者构成右螺旋关系。

Reflection characteristic simulation of plane waves in the dielectric surface

This paper use the electricity vector and magnetic vector to analysis the echoing characteristics of optical waves in two medium surface based on Maxwell electromagnetic theory,the electricity vector of the incidence,reflection and refraction waves of the plane optical waves is divided into two components: one parallel to the incidence angle,the other plumb to it,and the study of transformation relationship of reflectivity,transmission rate and phase with incidence angles when optical waves light from thin medium into the dense one and the optical waves light from dense medium into thin one is done combined with MATLAB.The amount of each parallel and vertical component shows with the index p and s to say,the three of s quantity,p quantity and propagation direction constitutions right spiral relationship.
