Special Issue Information

Dear Colleagues,

The Eleventh International Congress on Engineered Material Platforms for Novel Wave Phenomena—Metamaterials' 2017 (http://congress2017.metamorphose-vi.org/) will be held in Marseille, France from 28 August–2 September, 2017. From its first edition in 2007, the Metamaterials Congress has established itself as one of the most important forums worldwide for the engineering, physics, applied mathematics, and material science communities to share and discuss the latest results regarding artificially engineered materials and their applications in different fields, from electromagnetics and mechanics, to hydrodynamics and thermodynamics.

To continue this exchange of ideas and visions beyond the actual Congress, we are very glad to invite you to contribute to a Special Issue in Materials. This Special Issue will contain a selection of papers that derive their contents from either oral or poster presentations at the Metamaterials’ 2017 Congress. The purpose of this Special Issue is to provide a timely and broad collection of the topics discussed at the Congress. Manuscripts shall revolve around fundamentals of artificial materials and their design, electromagnetic, acoustic, and mechanical applications of metamaterials, metasurfaces and frequency selective surfaces, new wave phenomena, quantum aspects of metamaterials, plasmonics, nonlinearity and nonreciprocity, topological insulators, fabrication and measurements techniques, etc.

We invite researchers to submit their contributions, both original research articles and review papers, to this Special Issue and look forward to reading your submissions.

Self-assembled metamaterials attract considerable interest as they promise to make isotropic bulk metamaterials available at low costs. The optical response of self-assembled metamaterials is derived predominantly from the response of its individual constituents, i.e., the meta-atoms. Beyond effective properties, primary experimentally observable quantities, such as specific cross-sections, are at the focus of interest as they are frequently considered when exploiting metamaterials in specific applications. This posses the challenge of predicting these observable quantities for a diluted ensemble of randomly oriented meta-atoms. Thus far, this has been achieved by either averaging the optical response of the meta-atom across all possible incident fields or by restricting the consideration to only an electric and magnetic dipolar response. This, however, is either time-consuming or imposes an unnecessary limitation. Here, we solve this problem by deriving and presenting explicit expressions for experimentally observable quantities of metamaterials made from randomly arranged and oriented meta-atoms characterized by their T-matrix.

An open ring resonator (ORR) loaded with a varactor diode is designed and implemented in order to achieve high-performance tunable band-stop filters in planar technology with a compact size. This varactor-loaded ORR (VLORR) is versatile. It allows a shunt connection with different planar waveguide sections. In this paper, it has been connected to a coplanar waveguide (CPW) and a half-mode substrate integrated waveguide (HMSIW). As a reverse bias voltage is applied to the VLORR, a continuous tuning over the resulting stop-band can be achieved. To illustrate the possibilities of the VLORR, three prototypes have been designed, fabricated, and characterized. The three prototypes show an outstanding performance, with a rejection level at the resonant frequency and a tuning range greater than 12 dB and 85%, respectively. This VLORR has high potential value in microwave communication systems to eliminate unwanted signals. Full article
