Building the perfect lens with metamaterials

In principle a "perfect lens" could be created that opens up a brave new world of scientific investigation, particularly in nanotechnology and the biosciences. The key requirement of these instruments is to devise a cunning way of getting around the diffraction limit, which restricts the resolution of images produced with optical light. This film takes you to Imperial College London to investigate one promising route to a perfect lens that uses artificial structures known as metamaterials. This film is one of a three-part series exploring some of the most promising technologies that are emerging from physics research. The other films are here: ● Quantum Computing:    • Quantum Computing: A revolution in bits   ● Graphene:    • Graphene's potential to provide drink...   -------------- You can read about other physics spin-offs by downloading the special 25th anniversary issue of Physics World for free: ● http://physicsworld.com/cws/download/... ● Physics World is the member magazine of the Institute of Physics ● Physics World YouTube:    / physicsworldtv   ● Physics World Twitter:   / physicsworld
