One-Dimensional Kronig-Penney Model with Positional Disorder: Theory versus Experiment
摘要：
研究了一维Kronig-Penny模型中随机位置无序对波传播的影响。对于弱无序，我们推导出的本地化长度的解析表达式，并将其与有限样本的透射系数。所得到的结果很好地描述了实验的频率依赖性的微波实现的模型中的传输。我们的结果可以应用于光子晶体和半导体超晶格。
英文摘要：
We study the effects of random positional disorder in the transmission of waves in a 1D Kronig-Penny model. For weak disorder we derive an analytical expression for the localization length and relate it to the transmission coefficient for finite samples. The obtained results describe very well the experimental frequency dependence of the transmission in a microwave realization of the model. Our results can be applied both to photonic crystals and semiconductor super lattices.
