Flexible Metamaterials

  • by

Metamaterials (MMs) are man made materials with unusual electromagnetic properties that are not typically found in Nature. They are the key to achieving such extraordinary properties as invisibility cloaks and perfect lenses. At present, they are bulky and confined to laboratories. If they were flexible, they could become much more versatile and practical. We are working towards a novel concept for flexible MMs (Metaflex) that will turn current cloaking devices from suits of armour into true clflexible_metaoaks.


In the following figure a single layer of Metaflex is placed on a commercial disposable contact lens, to show the potential of the approach.


Our interest in Metaflex arises from diverse theoretical and experimental projects in photonic structures and nanofabrication and from the knowledge gained throughout these projects, including the physics and applications of MMs. This project contains many exciting scientific challenges, which offer the possibility of developing the extraordinary properties of MMs for every-day life applications that were unimaginable only a few years ago.

Recently we managed to demonstrate that it is possible to fabricate Metaflex with a fishnet meta-atom, with a resonance in the visible. This could be the first step towards three-dimensional flexible metamaterials at visible frequencies.
