Good point. I really should have said "visible frequencies". I used "optical" there to distinguish these metamaterials from acoustical metamaterials. I suppose that practically any wave phenomenon might be a candidate for this sort of treatment, as long as there are some regions (in frequency space) of highly dispersive effects for a given metamaterial. Perhaps not gravity waves, though.
I'm not sure about the resolution of the previous "negative refractive" lenses, but these things have been around for a few years. Pendry (I think) was one of the first to come up with the split-ring "metamaterial" and show that it can work, but the concept for these things has been around since Veselago came up with them, oh, about 40 years ago. People (including my advisor) have recently been proposing or demonstrating "negative refraction" acoustical materiaals, too. As far as I can make out from the summary, the OSU work is notable because this lens might work with optical frequencies, rather than in the radio and microwave regime, as previous optical metamaterials had to do.
Incidentally, people will find better information by searching for "left-handed" and "metamaterial" rather than "negative index" on the various sites.

The question is: what are you wanting to use your system for? Answer that before you start frontloading a lot of croft between you and the machine.
Huh. If I had Lara Croft frontloading anything, I for sure wouldn't be obsessing about WMs.
people arent afraid of robots because you can turn them off or reprogram them. if the situation gets deperate, you can "kill" them because they arent actually people or animals.
Oh, good. I don't have to be afraid of jetliners or cars or blenders any more!
Windows Vista will improve search functionality on a PC by letting users tag files with metadata, but those tags could cause unwanted and embarrassing information disclosure, Gartner analysts have warned.
On top of the obvious misspellings, your sentances are so poorly formed that it hurts my head to read them. I'm no grammar nazi, but at least try to get your sentance structure as intelligible as the point that you are trying to make... Please?
I'm no spelling nazi, but please learn how to spell 'sentences'.;)

3. Aluminum does not get hot in the oven. I've made thousands of fish sticks in the years after 1992, and no matter how badly I burn them, I can always lift them by the corners of the aluminum foil I placed them on.
How about this, smarty pants: fish don't have sticks!

I just find it ironic that you posted in response to "EvilMonkeySlayer".
Can an intelligence construct a world? Absolutely. Can we? No. Why not?
I'm sorry. This is slashdot. I want no mention of intelligence on this website! The answer to your question is implicit in the context.
3D interface? Check.
People claim they're intuitive. OK. Check.
Customizable? Check.
Probably no carpal tunnel problems, although maybe some strained necks.
Good enough.
It's also possible to appreciate and enjoy this science, whether or not you believe the algorithm's results.
What motivates theatres to have a "No NC-17" blanket policy?
Aaahhhhh. I've always wondered what to call those tin-foil emergency blanket thingies. Thanks!
The brest seurity is not the one done with the newest technology.
Damned right. Those hook-and-eye bras have been around forever, and I'll be damned if I can break into those easily.
Very much so, unless they ALSO have tinfoil hats.
What happens if you ferment a bunch of Abelian grapes in a Klein bottle?
I suppose you'd get very disoriented.
Wish I had mod points. I'm not saying which way I'd mod your post, but that's because I'm nonorientable. Nice one.

That's not pervasive computer. That's perversive computing.
You see, here we don't think theres any concidence that Microsoft and Multiple Sclerosis share the same abbrevation.
Multiple $clerosis?!?
You moron. There would be nothing to see: there's no light on the darkside of the sun.
Duh. It could carry solar-powered flashlights!
Why machines were invented. Who does crap manually?
Gosh. And here I was doing it without hands OR machines. I've gotta get with the times.
