Quasi-Continuous Metasurfaces for High-Performance Functional Electromagnetic Wave Devices

Dear Colleagues,

Metasurfaces are promising building blocks for functional materials and devices. However, traditional discrete designs often suffer from low efficiency and narrow bandwidth. Recently, quasi-continuous metasurfaces have been constructed with basic shapes such as arcs, trapezoids, and catenaries. Superior performances including higher efficiency and broader bandwidth have been reported. In addition, free-form quasi-continuous metasurfaces have attracted increasing attention, because they could exploit more degrees of freedom to optimize the metasurfaces.

In this Special Issue, the developing trends of quasi-continuous metasurfaces are highlighted. It would be a showcase of the diverse applications of quasi-continuous metasurfaces in both the optical and microwave regime, including but not limited to beam deflectors, flat lenses, wavefront modulators, perfect absorbers, antennas, etc.

It is my pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are all welcome.

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. Materials 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 2600 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.
