Special Issue Information
Dear Colleagues,
Dielectric nanoantennas have recently gained a lot of attention in many research areas, including sensing, solar cells, spectroscopy, and microscopy. The capability to excite either electric and magnetic multipolar resonances gives the possibility to shape the scattered light from such high-refractive-index structures in a desired manner. Moreover, they constitute the building blocks of the so-called metasurfaces.
Optical metasurfaces are 2D arrays of subwavelength scatterers designed to control properties of light ranging from its wavefront to polarization and intensity distribution or spectrum. The subwavelength resonators capture and re-emit the incident light. An appropriate geometrical choice of the dielectric nanoantennas that form the metasurface and of their mutual distance leads to the modification of the characteristics of light scattered from the 2D array. Thus, metasurfaces are attractive solutions in the miniaturization of bulk devices such as gratings, lenses, mirrors, holograms, waveplates, polarizers, and spectral filters.
Accordingly, this Special Issue seeks to showcase research papers and review articles that focus on novel dielectric nanoantennas, Mie resonators, reconfigurable metasurfaces, nonlinear optical phenomena, and new fabrication and characterization techniques.
I look forward to receiving your submissions!
Dr. Davide Rocco
Guest Editor
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. Micromachines 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 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.
