The invisibility cloak exists

It seems that Harry Potter’s invisibility cloak exists…in the lab at least:

SCIENTISTS in the United States have reported a further step towards a celebrated ”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 at Austin cloaked an 18-centimetre tube from light in the microwave part of the energy spectrum.

Those hoping for a Harry Potter-style touch of wizardry would be disappointed. To the human eye, the object was still visible.

But, say the researchers, the experiment is important proof of a principle that so-called plasmonic meta-materials can achieve a cloaking effect.

A war plane cloaked with such materials could achieve ”super-stealth” status by becoming invisible in all directions to radar microwaves, said co-lead investigator Andrea Alu.

When he’s not creating the news, he tends to be in it, with protagonists using the courts, media and social media to deliver financial as well as death threats.

They say that news is something that someone, somewhere, wants kept quiet. Cam Slater doesn’t do quiet and, as a result, he is a polarising, controversial but highly effective journalist who takes no prisoners.
