Scientists make cloak that hides objects
Almaty. February 3. Kazakhstan Today - Researchers have built an 'invisibility cloak' that can hide everyday objects by splitting light, the agency reports.
Scientists have built an "invisibility cloak" that can hide everyday objects by splitting light, The Independent reported.
The cloak, actually a lump of calcite crystal, can make objects like paper clips disappear from sight, Daily Mail informed.
Physicists from the University of Birmingham and colleagues from Imperial College, London, and Technical University of Denmark, said using the natural crystal enabled them to hide bigger objects than other researchers.
The team, led by Dr Shuang Zhang, from the university's school of physics and astronomy, glued two triangular pieces of calcite together, placed on a mirror.
The light enters the calcite and splits into two rays of different polarisations travelling at different speeds and in different directions.
Although the cloak itself is visible, it hides objects placed underneath it.
