Metamaterials with new electromagnetic properties
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.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
