Emerging Trends in Metamaterials and Metasurfaces Research

Dear Colleagues,

Metamaterials and metasurfaces are artificially structured materials crafted through the precise arrangement of metallic or dielectric inclusions, often organized in a periodic lattice. Crucially, the way these structures behave at the mesoscopic level is determined not only by the chemical composition of their constituent elements, but also by the specific geometric characteristics (size, shape, orientation, and more) of these elements. As a result, metamaterials and metasurfaces provide a multitude of design possibilities and, consequently, a wide range of physically attainable responses. These intricately engineered materials have the potential to yield unconventional and advantageous electromagnetic responses that extend beyond the capabilities of natural media. Their meticulous manipulation of electromagnetic fields and unprecedented control over electromagnetic wave propagation have positioned metamaterials and metasurfaces at the forefront of scientific research for over two decades. The objective of this Special Issue is to showcase the most current developments in metamaterial design and applications, with a focus on configurations offering advanced properties, versatile functionalities and intriguing applications. We invite you to submit a research paper on the theoretical aspects and/or practical applications of artificially structured media in this Special Issue of Photonics entitled “Emerging Trends in Metamaterials and Metasurfaces Research”.

We welcome submissions on topics that include (but not limited to) emerging trends on :

• Nonlinear metamaterials and metasurfaces;
• Reconfigurable and programmable (smart) metamaterials and metasurfaces;
• Spacetime-modulated structures;
• Metamaterials and metasurfaces for enhanced imaging capabilities;
• Active metamaterials and metasurfaces;
• Metamaterials and metasurfaces for biomedical applications;
• Metamaterials and metasurfaces for wavefront control;
• Topological metamaterials and metasurfaces;
• Extreme wave phenomena in metamaterials and metasurfaces；
• Metamaterial antennas and sensors.

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 250 words) can be sent to the Editorial Office for assessment.

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. Photonics 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 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.
