TL;DR
This paper investigates how correlations in generalized Thue-Morse superlattices affect wave localization and transmission, revealing significant changes in localization properties due to structural correlations.
Contribution
Introduces a generalized random Thue-Morse model as a four-state Markov process to analyze correlation effects on wave localization in superlattices.
Findings
Correlations significantly alter transmission properties.
Localization characteristics vary with frequency.
Structural correlations can enhance or suppress localization.
Abstract
In order to study an influence of correlations on the localization properties of classical waves in random superlattices we introduce a generalized random Thue-Morse model as a four-state Markov process with two parameters that determine probabilities of different configurations. It is shown that correlations can bring about a considerable change in the transmission properties of the structures and in the localization characteristics of states at different frequencies.
