Advanced Active and Passive Metasurfaces

Dear Colleagues,

Metasurfaces, the two-dimensional version of metamaterials, have attracted the interest of researchers in recent years. Among their interesting features, they can be easily fabricated by conventional techniques and present low losses compared to their three-dimensional counterparts, while still enabling an exceptional control of electromagnetic waves. Taking advantage of local and space-variant abrupt changes in phase, as well as amplitude and polarization of reflection and/or transmission, different electromagnetic responses can be achieved. For example, metasurfaces can be used to produce directive antennas, focusing systems, vortex beams with orbital angular momentum, surface Plasmons with extraordinary transversal confinement, non-reciprocal properties, digital coding and holograms.

This Special Issue on “Advanced Active and Passive Metasurfaces” in the journal Applied Sciences is aimed to summarize the recent advances in the development of active and passive metasurfaces and their related applications in the different fields of physics and engineering. The scope includes theoretical, computational and experimental contributions ranging from fundamental research to new designs and ideas for the development of advanced and functional applications of the metasurface concept.

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. 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.
