光波在左手材料中的菲涅尔公式和布儒斯特定律

Fresnel Formulate and Brewster Law of Optical Waves in the Left-handed Materials

根据Maxwell的电磁场理论,推导出单色平面光波入射到介电常量和磁导率分别为ε1、μ1和ε2、μ2的两种介质时的菲涅耳公式和反射率及透射率的普适表达形式·对于ε2<0和,μ2<0的左手材料,普适菲涅耳公式同样适用·研究了光从右手材料入射到左手材料时反射和折射的特性,给出了反射光为全偏光时布儒斯特角应满足的条件,此条件说明,在左手材料中布儒斯特角不但与折射率有关而且与磁导率有关·

Universal Fresnel formulae at the interface of two medium whose permitivity and permeability are ε1μ1 ,ε2μ2 are derived from Maxwell theory. The universal Fresnel formulae of the reflectivity and transmission coefficients are given. It is applicable for Right-handed materials and Left-handed materials. Analyzing properties of refection and refraction between two medium, the condition of Brewster angle are given in the Left-handed materials. The condition show that Brewster angle is not only relate to refractive index but also relate to permeability.
