Special Issue Information
Dear Colleagues,
The crystals occurring in nature display the possible types of symmetry enclosed in an abundance of different forms as a result of constitution and environment. The dynamics of the crystalline lattice is also responsible for the crystal’s physical behavior, initiating a connection of utmost importance between quantum mechanics and symmetry. Symmetry plays a great role in ordering the atomic and molecular spectra, for the understanding of which the principles of quantum mechanics provide the key. An exact classical analogue of a natural crystal is a three-dimensional (3D) phononic crystal. Mechanics and symmetry have played an important role in generating structures identified as mechanical metamaterials, the unique properties of which have extended the meaning of mechanical behavior and response to a new level.
The study of classical spectral-gap materials (photonic and phononic crystals) has produced over the last 3 decades the backbone for developing new exciting structures, known as metamaterials, exhibiting exotic properties in relation to regular materials, but most importantly, from a scientific point of a view, they serve as a classical realization of well-known condensed matter physics phenomena, such as Anderson localization, heat management, Dirac point topology, quasicrystals, cavity optomechanics, and many more.
With mechanics (sound and vibration) as the starting point, we explore, in somewhat unchartered regions, the possibilities of developing next-generation metastructures as a fusion of Physics, Engineering, and Applied Mathematics in creating methods, applications, sensors, and metamaterials of a new breed. For that new breed, one has to keep in mind two important aspects: smart and multifunctional.
Submissions of new and original ideas on the subject will hold absolute priority in this pioneering endeavor.

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. Applied Sciences 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 2400 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.
