Watch out Harry Potter, you are not the only wizard with an invisibility cloak.
Scientists at the University of Rochester have discovered a way to hide large objects from sight using inexpensive and readily available lenses, a technology that seems to have sprung from the pages of J.K. Rowling's Harry Potter fantasy series.
Cloaking is the process by which an object becomes hidden from view, while everything else around the cloaked object appears undisturbed.
"A lot of people have worked on a lot of different aspects of optical cloaking for years," John Howell, a professor of physics at the upstate New York school, said on Friday.
The so-called Rochester Cloak is not really a tangible cloak at all. Rather the device looks like equipment used by an optometrist. When an object is placed behind the layered lenses it seems to disappear.
Previous cloaking methods have been complicated, expensive, and not able to hide objects in three dimensions when viewed at varying angles, they say.
