Metasurfaces and Meta-Devices: From Fundamentals to Applications

Dear Colleagues,

Metasurfaces, as artificial two-dimensional structures, have become a transformative technology across numerous fields. Their appeal lies in their ultra-thin nature and unparalleled design flexibility, which enable precise, multi-dimensional control over classical waves like light, sound, microwaves, and heat. This capability unlocks groundbreaking applications, including flat miniaturized cameras, compact micro-manipulation systems, and new components for advanced communications.

The field is now in a vibrant state of rapid development. Research has moved beyond static wave manipulation to dynamic metasurfaces that can be actively tuned or passively switched. Their integration with other functional devices to form hybrid systems is also a key focus. At the fundamental physics level, exploration of non-Hermitian and topological physics within metasurfaces has led to the discovery of novel and intriguing wave phenomena.

This Special Issue aims to capture this dynamism by presenting cutting-edge research from various disciplines that utilize the versatile metasurface platform.

We look forward to receiving your contributions.

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-anonymized 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.
