Special Issue Information
Dear Colleagues,
Currently, there is a boom in studies on nanophotonics structures, as these systems possess a very high potential for integrated, multi-purpose optical devices, where sources, manipulation, and detection techniques of classical and quantum light can occur in a single chip. These devices may deliver impactful results in different fields of physics, such as communications, sensing, imaging, and automotive, to name a few. A very successful aspect of nanophotonics structures concerns their extreme versatility that allows the on-demand tailoring of their properties, such as emission, absorption, propagation, and storage of light, in a virtually arbitrary way. Among this vast and thriving research field, metamaterials have been the subject of extensive research in the last decades, because of their unique features in terms of local field enhancement and nonlinear properties at the ultrafast scale. Such physical processes involve heating and relaxation at time scales of the order of hundreds of femtoseconds, driving the electrons in such media out of equilibrium. The intricate dynamics resulting from out-of-equilibrium plasmas at such ultrafast scales is the main subject of this Special Issue, since it is expected to enable novel applications in nanophotonics, catalysis, and several other fields. In addition, this Special Issue aims at representing a reference for an emergent and active community, with the ultimate goal of providing inspiration for future research and collaborations within this community.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.
