Special Issue Information

Dear Colleagues,

We are inviting submissions to a new Special Issue on “Advances in Electromagnetic Metamaterials: Physics, Devices, and Applications”.

Electromagnetic (EM) metamaterial is a man-made material deliberately engineered to exhibit some electromagnetic properties that are difficult or impossible to find in natural materials. The novel properties of negative/zero index of refraction, sub-wavelength super lenses, electromagnetic invisibility cloaks, omnidirectional hyperreflective multilayer film, enhanced nonlinearity, etc., exhibit impressive applications that extend beyond those of conventional materials. The application techniques of EM metamaterials on optical filters, remote aerospace, medical devices, sensor detection, smart solar power collectors, radomes, optical communication and lenses, high-gain antennas, etc., are attracting increasing interest. The innovative concepts of metamaterials will lead to new phenomena and practical devices, which will be an important direction of future developments.

Research on electromagnetic metamaterial involves many different fields, such as electrical engineering, electromagnetics, optical engineering, solid state physics, microwave and antenna engineering, optoelectronics, material sciences, nanoscience, and semiconductor engineering.

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.

The interaction between an electromagnetic plane wave and a metallic wedge coated with a uniform layer made of a double-negative metamaterial is studied by means of the uniform asymptotic physical optics method in the high-frequency range, e.g., at microwave and optical frequencies. The apex angle of the structure is arbitrarily chosen, and the wave is at a skew incidence with respect to the external edge, which is formed by the metamaterial layers covering the wedge faces. The proposed method is built on the scattering integral involving electric and magnetic surface currents as physical optics equivalent sources, and it takes advantage of analytic evaluations. The last step uses a uniform asymptotic procedure to obtain a closed form expression of the diffracted field to be added to the geometrical optics one for computing the total field at the observation point in the neighboring free space. The study also includes a numerical validation of the method. Full article
