计算了光从真空-负折射率薄膜-真空,真空-负折射率薄膜-金属,正折射率介质-负折射率薄膜-真空以及真空-负折射率薄膜-正折射率介质四种复合结构中的负折射率薄膜表面反射的等效反射系数和GH位移.着重比较分析了在正折射率介质-负折射率薄膜-真空,真空-负折射率薄膜-正折射率介质两种结构中正折射率材料的吸收效应对不同入射极化波的GH位移的影响.
The effective reflection coefficient of the slab and the GH shift of the reflection light from the slab surface are computed for four different composite structures which consist of vacuum-negative reflective index slab-vacuum,vacuum-negative reflective index slab-metal,positive reflective index medium-negative reflective index slab-vacuum,and vacuum-negative reflective index slab-positive reflective index medium,respectively.It is emphasized that the effects of the absorption of the positive reflective index medium on the GH shifts of the TE-and TM-polarized waves are compared in the last two circumstances.
