Abstract

Flexible manipulation of elastic and acoustic waves through phononic meta-structured materials (PMSMs) has attracted a lot of attention in the last three decades and shows a bright future for potential applications in many fields. Conventional engineering design methods for PMSMs rely on changing the material composition and empirical structural configurations, which often result in limited performance due to the limited design space. Recent advances in the fields of additive manufacturing, optimization, and artificial intelligence have given rise to a plethora of creative meta-structured materials that offer superior functionality on demand. In this Review, we provide an overview of inverse design of phononic crystals, phononic-crystal devices, phononic metamaterials, phononic-metamaterial devices, phononic metasurfaces, and phononic topological insulators. We first introduce fundamental wave quantities including dispersion relations, scattering characterizations, and dynamic effective parameters, and then discuss how these wave quantities can be leveraged for systematic inverse design of PMSMs to achieve a variety of customized phononic functionalities with highly customizable full-wave responses, intrinsic physical parameters, and hybrid local–global responses. Furthermore, we show representative applications of some inverse-designed PMSMs and look at future directions. We outline the concept of phononic structures genome engineering (PSGE) through key developments in PMSM inverse design. Finally, we discuss the new possibilities that PSGE brings to wave engineering.

声波元结构材料的逆向设计
通过声子元结构材料(PMSMs)灵活操纵弹性波和声波在过去三十年里引起了广泛关注,在许多领域的潜在应用前景广阔。PMSMs 的传统工程设计方法依赖于改变材料成分和经验结构配置,由于设计空间有限,往往导致性能受限。增材制造、优化和人工智能领域的最新进展催生了大量创造性的元结构材料,可按需提供卓越的功能。在本综述中,我们将概述声波晶体、声波晶体器件、声波超材料、声波超材料器件、声波超表面和声波拓扑绝缘体的逆向设计。我们首先介绍了包括频散关系、散射特性和动态有效参数在内的基本波量,然后讨论了如何利用这些波量对 PMSMs 进行系统反设计,以实现各种定制的声波功能,包括高度定制的全波响应、固有物理参数和局部-全局混合响应。此外,我们还展示了一些反向设计 PMSM 的代表性应用,并展望了未来的发展方向。我们通过 PMSM 逆设计的关键发展,概述了声波结构基因组工程 (PSGE) 的概念。最后,我们讨论了 PSGE 为波浪工程带来的新可能性。
