Abstract
The acoustic characteristics of one-dimensional generalized Thue-Morse quasi-periodic structures using serial closed resonators with varying cross-section areas are examined in this work. The localization and the acoustic band gap features are analysed by systematically altering the complexity of the generalized Thue-Morse sequences. The findings show that higher-order generalized Thue-Morse sequences introduce stronger localized modes and wider acoustic band gaps, which allow for control over wave propagation. We demonstrated the role of using resonators with different cross-section areas to enhance wave confinement and band gap tunability. Results show the potential use of the proposed generalized Thue-Morse structures in high-sensitivity sensors, multi-frequency resonators, and tunable filters, among other advanced acoustic applications.
