Scientists Make 'Invisibility Cloak' Breakthrough -- The Telegraph
Scientists in the United States have made a further step towards creating an "invisibility cloak" by masking a large, free-standing object in three dimensions.
The lab work is the latest advance in a scientific frontier that uses novel materials to manipulate light, a trick that is of huge interest to the military in particular.
Reporting in the New Journal of Physics, researchers at the University of Texas in Austin cloaked a 7.2-inch cylindrical tube from light in the microwave part of the energy spectrum.
Those hoping for a Harry Potter-style touch of wizardry will be disappointed however. To the human eye, which can only perceive light in higher frequencies, there would have been no invisibility.
