摘要：
人工蛋白石的反射和透射特性通过一种基于有效折射率一维变化的分层介质模型来描述。该模型尤其适用于Langmuir-Blodgett（朗缪尔-布洛杰特）型无序蛋白石，光散射通过唯象吸收来解释。蛋白石与衬底（或真空）之间的界面区域会导致光子晶体结构的周期性中断，这对反射特性有显著影响，尤其是在布拉格反射峰以外的区域。实验结果与我们的模型进行了对比。该模型可扩展至反蛋白石、堆叠圆柱或倏逝波照射场景。
英文摘要：
Reflection and transmission for an artificial opal are described through a model of stratified medium based upon a one-dimensional variation of an effective index. The model is notably applicable to a Langmuir-Blodgett type disordered opal. Light scattering is accounted for by a phenomenological absorption. The interface region between the opal and the substrate -or the vacuum- induces a periodicity break in the photonic crystal arrangement, which exhibits a prominent influence on the reflection, notably away from the Bragg reflection peak. Experimental results are compared to our model. The model is extendable to inverse opals, stacked cylinders, or irradiation by evanescent waves
