Research Progress of Crystalline Metamaterials

Dear Colleagues,

A metamaterial is any substance that has been designed to possess a characteristic that is exceptional in naturally existing materials. Furthermore, the qualities of these artificially made composite materials are determined by their internal structure rather than their chemical composition in contrast with conventional materials. Because of this, the development of metamaterial structures provides properties and abilities that are challenging to accomplish with traditional materials. Initial research on unconventional materials focused on the unusual electromagnetic properties of isotopic, homogenous metamaterials, such as reversed Cherenkov radiation, the negative refractive index, and reversed Doppler effect, where the values of permeability and permittivity were negative. The primary cause of metamaterials’ great interest is their remarkable effect on light traveling through them. Metamaterial technology has the potential to be advantageous to almost every research field currently in development due to its unique acoustical, electromagnetic, optical, and mechanical properties. These fields include telecommunications, metadevices, defense, biomedical imaging, sensing, electromagnetic absorption reduction, radar-cross section reduction, crystalline metamaterial, etc. Even though crystalline metamaterials have a subwavelength spatial scale, which often entails ignoring their structure, they can nonetheless acquire complicated foreign features due to multiple scattering. In addition, this material may contribute to the unique importance of resonant multiple scattering in prompting novel and intriguing features, namely topological characteristics, at the deep subwavelength scale. The purpose of this Special Issue is to provide a platform for recent developments in the fields of crystalline metamaterials theory, numerical modeling, experiments, and current work in coding and conventional metamaterials-based applications. The growth of the future electronic industry is aided by the innovative material features and device capabilities made possible by metamaterial technology.

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.
