Multifunctional Metasurfaces: Design Strategies and Applications

Dear Colleagues,

As the planar version of metamaterials, metasurfaces have attracted wide interest recently due to their enriched degree of freedoms to manipulate and control electromagnetic (EM) waves. However, conventional metasurfaces are mainly designed to control a single physical aspect (i.e., either phase, frequency, polarization, or amplitude) of EM waves, and thus cannot satisfy the requirements of modern photonic applications for multifunctional integration and miniaturization. Therefore, one ongoing trend is to perform different functionalities with a single metasurface.

In this Special Issue, the developing trends of multifunctional metasurfaces will be highlighted. This Special Issue aims to be a showcase of the design strategies and diverse applications of multifunctional metasurfaces, from optical to microwave regimes.

It is my pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are all welcome. Topics of this Special Issue include, but are not limited to, the following:

• Spatially multiplexed metasurface;
• Tunable and intelligent metasurface;
• Vectorial metasurface;
• Full-space metasurface;
• Space–time-coding metasurface;
• Topology optimization;
• Adjoint optimization;
• Deep learning.

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.
