Abstract

This work analyzes the propagation of acoustic waves in quasi-periodic structures for filter applications. The study focuses on a proposed one-dimensional quasi-periodic structure employing generalized Thue–Morse sequences. The suggested configuration consists of two basic building blocks: the block ‘X’ is a parallel configuration of closed resonators grafted on the main duct. The block ‘Y’ has a single open resonator integrated into the same main duct. Using the transfer matrix method and finite element method, the study investigates the acoustic bandgap characteristics of Thue–Morse. The present work leverages both methods, comparing their predictions and emphasizing the impact of multidimensional effects, particularly in the context of Thue–Morse sequences. Besides, the results show that acoustic band gaps can be tuned, and there are localized modes that can help filter waves and suppress high-frequency noise.

采用有限元法和传递矩阵法对Thue-Morse结构进行选择性滤波

本文分析了声波在滤波器准周期结构中的传播。研究了一种基于广义Thue-Morse序列的一维拟周期结构。建议的配置由两个基本构建块组成：块“X”是接枝在主管道上的封闭谐振器的平行配置。块“Y”有一个单独的开放谐振器集成到同一主管道。采用传递矩阵法和有限元法，研究了Thue-Morse的声带隙特性。目前的工作利用了这两种方法，比较了他们的预测并强调了多维效应的影响，特别是在Thue-Morse序列的背景下。此外，结果表明，声带隙可以调谐，并且存在有助于滤波波和抑制高频噪声的局域模式。

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
