Special Issue "Nanomaterial-Based Wavefront Manipulations and Applications"

Dear Colleagues,

The diffraction limit, discovered in 1873 by Ernst Abbe, follows on from the general Heisenberg uncertainty relations, and is one of the limitations on the resolution of optical information systems, and on the minimum size on lab-on-chip systems. This fundamental limit can be overcome with the help of photonic–nanostructured devices—for example, the localized electromagnetic fields formed in the shadow surface of a mesoscale dielectric particle with a refractive index contrast near 2 can be modulated by introducing a nanohole structure at its rear surface, which makes it possible to improve the spatial resolution well beyond the stable immersion diffraction limit. On the other hand, various exotic optical phenomena, such as the focusing of light beyond the diffraction limit and nonlinear photonics, arise from the collective interaction of many nanostructures specially organized to produce an ordered artificial material.

This Special Issue aims to bring together fundamental and theoretical (including simulations) as well as experimental studies in the form of high-quality papers in the field of nanomaterial-based wavefront manipulation.

Topics will include, but are not limited to:

• Sharp-edged structures;
• Sharp metal tips;
• Super-resolution focusing by nanostructured materials;
• Functionalized nanomaterials-based devices;
• Nanomaterial-based optical laser lithography beyond the diffraction limit;
• Nanomaterials-based vortex generators;
• Design and fabrication of nanoscale structures with desirable physical, scattering and morphological properties;
• Two-dimensional-nanomaterials-based electronic devices;
• Sensing, trapping, nano-manipulation and other applications of nanomaterial-based sharp focusing devices.

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. Nanomaterials 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.
