根据Maxwell电磁场理论,推导出线偏振单色平面波的普适菲涅尔表达式,得到特异材料反射相移计算公式.利用反射相移公式研究了线偏振单色平面波从空气入射到单负材料(ε＜0或μ＜0 )时分界面处反射相位的特性.结果表明单负材料界面处反射相位连续变化,与传统材料全反射的相位变化特点相似.

Based on the Maxwell equation,the Fresnel formulae is generalized to the metamaterials,from which the formula for calculating the phase shift of reflective wave is obtained.The reflective phase changes at the interfaces between single-negative materials and positive materials are studied.The results show that the reflection from the interfaces of the single-negative materials is similar to that of the total reflection of the conventional materials.
