Study and realization of metamaterials for electronics and TLC applications

Università degli Studi Roma Tre
Abstract
The research program integrates the expertise, the resources and the experimental facilities of five academic institutions in order to conceive, design and experimentally realize innovative microwave components loaded with different types of metamaterials. The latter materials exhibit anomalous physical properties not readily available in nature and are capable of exhibiting surprising phenomena not achievable through the employment of conventional materials.
The research results within the scientific community in this field opens the door to new exciting capabilities in the near future for electronic and telecommunication industry through the design of miniaturized components, multifunctional and higly directive radiating components, imaging systems, unimodal cavities with a very high quality factor, ultracompact filters, ultrafast switches, delay lines, low power microlasers, systems for ultrafast optical computation, etc.
The present research program is focused, mainly, on microwave applications of different classes of metamaterials, such as negative refractive index metamaterials (Double NeGative - DNG), materials characterized by negative constitutive parameters (Single NeGative - SNG), Electromagnetic Band Gap (EBG) materials, materials made by planar printed periodic structures.
In this frame, it is proposed to develop the theoretical modeling for the analysis, the numerical codes for the simulation and optimization, the fabrication and >>>

Research Objectives
The goal of the present research is to conceive, design and fabricate high-tech innovative microwave components outperforming those based on conventional components. To this end, the research units involved in the project will exploit different types of metamaterials - artificial materials exhibiting anomalous properties not readily available in nature - such as DNG, SNG and EBG media (see the Scientific Background of the research program for the definition of the different materials and the description of their features).

The surprising features of DNG and SNG metamaterials, their easy large-scale fabrication (see the section on the scientific background), and the preliminary results obtained by several different groups, allow nowadays to employ DNG/SNG metamaterials as an effective device to overcome the traditional limits of current electronic and microwave devices realized with conventional materials. Particularly, in the frame of the proposed project, DNG/SNG metamaterials are employed to overcome the diffraction limit, which states that the dimensions of the traditional components have to be comparable with the operating wavelength. The combined use of standard dielectrics and metamaterials allows to overcome the aforementioned limit and conceiving new miniaturized components, to be employed in several applications. On the other hand, the employment of DNG/SNG metamaterials to achieve specific performances from radiating and transmissive components, not >>>

National and international background
With the term "metamaterials" we refer to the wide family of artificially engineered electromagnetic materials and, thus, not existing in nature, designed through the embedding of given inclusions with proper shape and dimensions in a host medium. The shape, the dimensions, the alignment, and the location of the inclusions are designed in such a way to modify the electromagnetic features of the host dielectric and obtain particular features that, for the application of interest, cannot be obtained through the employment of standard materials. Due to the recent advances in the fabrication technology, the theoretical modeling of such materials represents nowadays a relevant aspect of the research.

There is nowadays a sustained interest in metamaterials with a negative refractive index (or Double NeGative - DNG materials) [1], due to their anomalous features that can be used in several promising electromagnetic applications. The study of their features, theoretically anticipated by Veselago in 1968 [2], dealt with a tremendous explosion of interest in the last years, since the first samples have been successfully fabricated and measured at the University of California at San Diego [3]. The synthesis of such materials, obtained exploiting the combined resonances of metallic inclusions having wire (electric dipoles) and split ring resonators (magnetic dipoles) shapes, has been improved in the last few years and the current technology allows to synthesize >>>
