Dear Colleagues,

Many efforts have been invested to understand the outstanding electromagnetic properties of carbon nanotubes, graphene, and other forms of nanocarbon, their composites, metasurfaces, and porous structures.

In order to predict the electromagnetic response of an ensemble of individual inclusions, their electromagnetic response should be modeled by means of ab initio calculations, semiclassical theory, and classical electromagnetics, in combination with relevant effective medium and percolations theories/simulation strategies. Regular and irregular structures, metamaterials and metasurfaces, and architectures made of those compositions are further numerically or, in the case of simple geometries, analytically modeled, closing the loop.

Plenty of experimental techniques are known to be able to obtain a wide collection of data, including broadband dielectric spectroscopy, microwave waveguide and free-standing measurements, free electron lasers and backward oscillators generating high- and low-power THz and GHz pulses, voltammetry, impedancemetry, and many others, which allow gathering complementary knowledge of the electromagnetic behavior of materials and devices. Along with conventional approaches, highly sensitive resonator-based and photonic jet approaches allow monitoring electromagnetic properties with super-resolution.

Tuning and adjusting the constituent properties of materials (nano, meta, and composites) allow designing a variety of electromagnetic devices, both passive and active, whose robustness may be controlled at many levels, e.g., through control of the influence of nanomaterials’ imperfection on the final performance, analysis of deviation at the stage of technological steps of material/device fabrication, and due to the measurements.

All these subtopics represent the focus of the present Special Issue on theoretical and experimental electromagnetics of graphene and nanocarbon materials.

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. Materials 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.
