Cloaking device puts the kibosh on cellphone interference

There has been plenty of research into cloaking devices, but while scientists are still working their way towards the visible light spectrum they seem to be having the best luck with microwaves. Most recently, a new metamaterial made from over 10,000 individual pieces of fiberglass has been used to cloak a bump on a flat mirrored surface -- the material prevents microwaves from being scattered, giving the RADAR (we're guessing it's a RADAR) the impression that the surface is flat. This has many possible applications, such as cloaking sources of interference to cellular communications. Unfortunately, the implication we most desire -- rendering us invisible during high society jewel heists -- has yet to become reality. 
The Klingons are going to be pissed off by this.
Hahahhahah, LOL.... Good one. It may seem sad, but it made my night.
this will be great until google buys that spectrum too.
Google bluffed - they own no spectrum.
Bu Bu Bu... what if i need to cook my food while cloaked? Can I still cook with my microwave?!
Cloaked a bump, huh? I see a new acne-fighting measure.
Yes, you'll just need this and then to make everyone look at you with RADAR instead of, you know, vision.
I wonder if this type of tech could be used to protect moon colonies from radiation.
zack morris FTW
At least we may have one defense against our future robot overlords.
Wouldn't this have use in stealth aircraft? instead of a small RADAR cross section, a plane would have none as all
It's a cool idea but this 'cloak' must be compared to a background of the same material. If I am not mistaken there is an article about the experiment (sorry no copy/paste but it is on the msnbc news mobile home page right now) that I read today as well.
I know Msnbc.com same day as engadget. I know. Wow.
No copy paste?
Running fruit I guesss?
Stealth car
No more speeding tickets
Hmm, I'll take the risk of being a dork here, but materials that prevent reflection of radiation back to the source have nothing to do with "cloaking" or general invisibility. That's like saying a big black blanket over the thing being cloaked would be an equivalent material for this in the visible spectrum.
For the thing that gets coated in the material to be cloaked (in visible or other spectrums), a light/radiation source that is behind the object would still have to be "visible" to the eye/detector, as though the light went through it.

This is just stealth technology, snore.
