Science fiction fans are one step closer to having their dreams realised thanks to Slovak and Spanish electrical engineers who have developed a prototype invisibility field. The researchers used simple materials, such as a superconductor, and ferromagnetic materials that are freely available on the market to create an invisibility field that can effectively hide contents […]

Progress of metamaterials in nanotechnologies has made the invisibility cloak, a subject of mythology and science fiction, become reality: Light waves can be guided around an object to be hidden, in such a way that this object appears to be non-existent. This concept applied to electromagnetic light waves may also be transferred to other types […]

Humans generally recognize objects through two features: their shape and color. To render an object invisible, one must be able to manipulate light so that it will neither scatter at an object’s surface nor be absorbed or reflected by it (the process which gives objects color). Researchers at Northwestern University have created a new kind […]

An Invisible Man with perfect vision sounds like a superhero from a comic, but may be close to reality thanks to scientists at the University of St Andrews. A team of physicists are one step closer to creating a Harry Potter-style invisibility cloak, with a new form of material that could also be attached to […]
