Researchers say they have derived the physical properties required to make an invisibility cloak. Once the stuff of science fiction and Harry Potter fantasy, scientists now say that a practical invisibility cloak could be made from a material that uses light reflected off of nearby objects combined with the same light bouncing off itself to cancel it out. This light scattering and cancellation approach differs from other prototypes using transformation thermodynamics, and the researchers say it could be simpler to fabricate. Such a device has many possible applications in engineering, including advanced medical imaging.
