Special Issue Information

Dear Colleagues,

Architected periodic structures like phononic crystals and elastic metamaterials offer unprecedented opportunities for elastic wave manipulation, unachievable using traditional homogeneous materials. Since their introduction, these structures have been exploited to generate effects like frequency band-gaps, negative refraction, topological protection, non-reciprocal propagation, etc. In parallel, recent advances in material science and technology, including additive manufacturing, have allowed the practical realization of a huge variety of novel complex structures at various different length scales, leading to additional application opportunities in the field of wave control, focusing and collimation, environ-mental noise reduction, and even earthquake protection. The fast growth of the topic and increasing interest in the field from researchers with expertise in the areas of material science and beyond are the main reasons for this Special Issue on “Advances in Acoustic Metamaterials”. Contributions should focus on new achievements, both theoretical and experimental, relative to the dynamics of phononic crystals and metamaterials, related (but not limited) to effects such as negative refraction, stop-band filtering, cloaking, focusing, energy harvesting, topological states, etc.

The issue is intended to provide a platform for researchers working in the field to disseminate their ideas on the design and characterization of new configurations, highlighting novel dynamic phenomena and exploring additional promising applications. It should also stimulate a cross-fertilization between researchers of the field with other readers of the journal, providing the opportunity to find new potential research directions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs).

We present an acoustic metamaterial (AMM) consisting of a dumbbell-shaped split hollow sphere (DSSHS). Transmission results of experiments and simulations both presented a transmitted dip at the resonant frequency of AMM, which demonstrated its negative modulus property. As the two split holes in the DSSHS had strong coupling effects for the acoustic medium in the local region, the dip could be simply manipulated by tuning the distance between the split holes. When the distance was large enough, the mutual inductance tended to disappear, and a weak interaction existed in the structure. According to the property of weak interaction, a multiband AMM and a broadband AMM with a negative modulus could be achieved by arraying DSSHS clusters with different distances. Furthermore, mutual inductance and coupling in DSSHS reinforced the local resonance, and this kind of cell could be used to design the acoustic metasurface to abnormally control the refractive waves.
