Abstract

A methodology for constructing a quasi-one-dimensional coupled-resonator phononic metamaterial is presented. This is achieved through the design of artificial phononic analogs of two molecular structures: trans-polyacetylene and trans-polyaminoborane. The band structure of trans-polyacetylene is analyzed in relation to the Su–Schrieffer–Heeger (SSH) model, while that of trans-polyaminoborane is examined using the

κ

-deformed Dirac equation, both within a tight-binding framework. Additionally, the obtained finite realization of the artificial trans-polyacetylene exhibits topologically protected states.

耦合谐振腔声子聚乙炔和聚氨基硼烷的能带结构工程

提出了一种构造准一维耦合谐振腔声子超材料的方法。这是通过设计两种分子结构的人工声子类似物来实现的：反式聚乙炔和反式聚氨基硼烷。用Su-Schrieffer-Heeger （SSH）模型分析了反式聚乙炔的能带结构，用κ-变形狄拉克方程分析了反式聚氨基硼烷的能带结构，两者都在紧密结合的框架内。此外，所获得的人工反式聚乙炔的有限实现呈现拓扑保护状态。

期刊介绍： The International Journal of Solids and Structures has as its objective the publication and dissemination of original research in Mechanics of Solids and Structures as a field of Applied Science and Engineering. It fosters thus the exchange of ideas among workers in different parts of the world and also among workers who emphasize different aspects of the foundations and applications of the field. Standing as it does at the cross-roads of Materials Science, Life Sciences, Mathematics, Physics and Engineering Design, the Mechanics of Solids and Structures is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from the more classical problems of structural analysis to mechanics of solids continually interacting with other media and including fracture, flow, wave propagation, heat transfer, thermal effects in solids, optimum design methods, model analysis, structural topology and numerical techniques. Interest extends to both inorganic and organic solids and structures.
