Wow, that's cool.

"However, for applications to come within reach, several goals need to be achieved," he added. "First, reduction of losses by using crystalline metals and/or by introducing optically amplifying materials; developing three-dimensional isotropic designs rather than planar structures; and finding ways of mass producing large-area structures."

Well dur.

Wait, so it actually absorbs more light than is shined on it?

Be patient with me, I went to Texas public schools.

First off, LaChanz won the thread before it even got started.

Uh... that stuff has been around since at least the 70's. Wonderwoman has a plane made out of it.

This, by the way, doesn't mean that it's impossible to *see*--but it would be useful as all get-out versus, for instance, the speed-trap on the interstate.

Not sure how this would work in broad daylight, I would imagine if you were wearing a cloak of this material, you would not be invisible but rather a lump of disfigured light diffractions?

Well, props to subby for using an internet cliche when it was finally appropriate!

Does that make it ironic, also?
 
2007-01-05 09:23:25 AM
What does this mean:
"Metamaterials, also known as left-handed materials"

Handedness? really?

Hondaman4ever: Not sure how this would work in broad daylight, I would imagine if you were wearing a cloak of this material, you would not be invisible but rather a lump of disfigured light diffractions?

from reading TFA and a few side articles I found on it, it seems more likely that you would be invisible in the red spectrum which would do jack shiat other than make you look like some blob in the distance in daylight.

However at night, you would be practically invisible and anything using the red spectrum to enhance the image (night vision, thermal optics, etc..) it would render you darker against the rest of the background making you a harder target to aquire.

The military is going to be all over this like a fly on shiat.

The colour of the cloak would not be what you expected it to be, and it would look like the light source illuminating it was coming from somewhere else--but I don't think it'd be all psychedelic colours.

Has been. This is something that certain Farkers I know of have been talking about for a while.

If precedent holds, this announcement means that they probably have already applied said material to something and that that something is in production.

Great headline.
And kudos to LaChanz for a great opening response.
 
2007-01-05 09:26:28 AM
From the wiki: Metamaterials ... have numerous startling properties: ...The Doppler shift is reversed (that is, a light source moving toward an observer appears to reduce its frequency) .

That's crazy!
 
2007-01-05 09:27:24 AM
Ahhhh........brilliant.

/good start to FFrarkiday.

muninsfire: If precedent holds, this announcement means that they probably have already applied said material to something and that that something is in production.

I seem to remember the same thing being said about stealth materials for radar. Researchers announcing that they were able to deflect incoming wavelengths and scatter them or trap them using specific formed structures thus reducing their signal strength.

Low and behold, some years later everyone knew about the SR71.

Full-wave verification of the fundamental properties of left-handed metamaterials (LHM) in waveguide configurations

This is how senior scientists haze the new interns: "Hey Bob, go find me some left-handed metamaterial I need for this crucial experiment."

So...could you then tell the speed of a yellow bullet by how green it appears?

Thanks for the flashbacks to "Battlestar Galactica: 1980"

Yep.

It's pretty standard. It'll be fun to watch when the SpookyFarkers show up; always is.
 
2007-01-05 09:40:26 AM
No doubt they forgot to convert standard to metric.

"...darker against the rest of the background..." Isn't that known as "contrast?" I better change my trout fishing tactics; instead of using a dark colored streamer which appears darker then the night sky, I'll use something just about the same color as the night sky, so it's an easier target for the trout below to acquire.

"Left-handed materials may one day lead to the development of a type of flat superlens that operates in the visible spectrum,"

I immediately lose interest in any new development when they say that it "may one day lead to...", to me that means never in my lifetime, so it's not cool.

Shouldn't be too hard; the way I hear it, only the top-end models are even capable of speech.

PYROY: I immediately lose interest in any new development when they say that it "may one day lead to...", to me that means never in my lifetime, so it's not cool.

Psst. When it's the government talking, it means they already have it in production and they're just now telling people about it existing--because they're developing something newer and better, and can afford to let it out now.

"Left-handed materials may one day lead to the development of a type of flat superlens that operates in the visible spectrum," said Soukoulis, who is also an Iowa State University Distinguished Professor of Liberal Arts and Sciences. "Such a lens would offer superior resolution over conventional technology, capturing details much smaller than one wavelength of light to vastly improve imaging for materials or biomedical applications," such as giving researchers the power to see inside a human cell or diagnose disease in a baby still in the womb.
