Look out, Harry!

This image is an example of an approximate "invisibility cloak" that was developed at Tokyo University a few years ago. There has been another recent development on this front, albeit in the microwave not the visible part of the spectrum.

My friend Tawfik forwarded the news item below to me so I can tell Moody that science is catching up with Mr. Potter. The only problem is, the cloak itself is still visible! Maybe there is a self-reference paradox in that... Nah, I'm just lying! lol

An invisibility cloak that works in the microwave region of the electromagnetic spectrum has been unveiled by researchers in the US. The device is the first practical version of a theoretical set-up first suggested in a paper published earlier in 2006.

The cloak works by steering microwave light around an object, making it appear to an observer as if it were not there at all. Materials that bend light in this way do not exist naturally, so have to be engineered with the necessary optical properties.
