Scientists Create Artificial Mini 'Black Hole'

ScienceDaily (June 3, 2010) — Chinese researchers have successfully built an electromagnetic absorbing device for microwave frequencies. The device, made of a thin cylinder comprising 60 concentric rings of metamaterials, is capable of absorbing microwave radiation, and has been compared to an astrophysical black hole (which, in space, soaks up matter and light).

The research published June 3 in New Journal of Physics (co-owned by the Institute of Physics and German Physical Society), shows how the researchers utilised the special properties of metamaterials, a class of ordered composites which can distort light and other waves.

Qiang Cheng and Tie Jun Cui of the State Key Laboratory of Millimeter Waves at Southeast University in Nanjing, China, designed and fabricated their absorbing device, officially called an "omnidirectional electromagnetic absorber," using 60 strips of circuit board arranged in concentric layers coated in copper. Each layer is imprinted with alternating patterns, which resonate or don't resonate in electromagnetic waves.

The designed device can trap and absorb electromagnetic waves coming from all directions by spiraling the radiation inwards and converting its energy into heat with an absorption rate of 99%. Hence it behaves like an "electromagnetic black body" or an "electromagnetic black hole."

1. hmm, maybe the Chinese will develop the Cloaking Device before us.

3. Does it bend light? (of any frequency)

4. Well, I have not seen it, so I would guess yes

5. Pretty good!
I almost started a serious reply before I got it.

6. Hmm... Radar uses microwaves.
This would be invisible to radar, right? Just sayin.

7. Shit, I thought it was a real black hole
That would have been a major breakthrough.

11. Not really. A mini black hole would evaporate in nanoseconds.
If it's possible to produce one, the cosmic rays that hit the upper atmosphere have been making them for billions of years.
