Special Issue Information
Dear Colleagues,
Acoustic metamaterials (AMMs) are a form of synthetic material that can be specifically developed to have a sub-wavelength periodic structure with extraordinary characteristics not found in nature. Recently, the ability to manipulate sound waves, elastic waves, and seismic waves thanks to these properties has attracted great interest from scientists and engineers and has been the subject of extensive research. Acoustic metamaterials have a broad range of applications, including sound absorption/isolation, noise control, medical imaging, architectural acoustics, defense and security, energy management, earthquake resistance, and underwater applications. Although acoustic metamaterials have tremendous ability for the field of sound control, AMMs present challenges such as frequency-dependent operation, optimization requirements, and material costs. Some interdisciplinary theories on acoustic metamaterials have been proposed in this field, such as intelligence, nonlinearity, topology, and bound state in the continuum (BIC). These challenges and multidisciplinary theories are current and relevant topics. This Special Issue, entitled “Research and Applications of Acoustic Metamaterials”, will report the progress achieved over the past several years.

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 submissions that pass pre-check are 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. Crystals is an international peer-reviewed open access monthly 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 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
