Metamaterials with new electromagnetic properties

25.03.2004


The development of new types of artificial materials, known as “metamaterials” and with electromagnetic properties not found in nature, is the aim of the Metamorphose Excellence European Network, of which the Public University of Navarre forms part, together with twenty-one other research institutions from 13 European countries.



Perfect plane lenses

Metamaterials are electromagnetic and multifunctional artificial materials, created in order to comply with certain specifications. They involve materials that have properties superior to those found in nature. Development of these materials will give rise to new optical, microwave and radio technologies, based on new revolutionary materials which derive from the large-scale amalgamation of basic elements (nanoscopic and microscopic) in heretofore unprecedented combinations.


These electromagnetic materials are destined to fulfil a fundamental role in the function and enhancement of the electronic devices and components of the future, such as high-speed circuits, multifunctional and miniature aerials, high-resolution image systems and garment-integrated communication systems, amongst other applications. In the last analysis, these systems are built from substrates and superstrates the electromagnetic response functions of which determine the design and operation of systems.

For example, recently the theoretical concept for perfect planar lenses made with negative-refraction index (“left-handed”) metamaterials. These perfect lenses would enable resolution limitations in many optical and electromagnetic systems to be overcome and go beyond the diffraction limits of conventional materials. Just with this concrete example multiple applications in several information technology and life science areas can be predicted such as, for example, enhanced image systems, higher capacity systems for the optical storage of data, more compact integrated optical telecommunications solutions.

Creation of a Virtual Research Institute

The joint activities of the Metamorphose Network are to involve research on composite materials with extreme electromagnetic properties (such as left-handed mediums and materials with negative-refraction indexes), electrically controllable material, quasi- periodical fractals and structures, artificial surfaces, etc.

It can also be pointed out that the strategic aim of development of new metamaterials involves the opening of a new line of research in the multidisciplinary field of materials physics, electromagnetism, optics, radio and electronic engineering. Moreover, Metamorphose wishes to serve as a tool in joint research through the creation of a Virtual Institute which will pull together efforts in key research areas, extending excellence and transferring the new technology to European industry. This Institute is expected to continue functioning once the EU funding period expires, co-ordinating, managing and controlling the joint research projects of the participating bodies and institutions.

There is also a plan to create an international PhD programme in this new field, as well as a university school for metamaterials.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
