Using the Terahertz Spectrum for Wireless Communication
holy_calamity writes "A first step to allowing wireless data transfer over a currently unused part of the electromagnetic spectrum is reported in New Scientist. Terahertz radiation exists between radio and infrared. A new filter created at the University of Utah can filter out particular frequencies, a prerequisite for using it for data. The abstract of the paper in the journal Nature is freely available."
10 years? Anyone?
Pshaw, that's nothing. I work with high end audio equipment, and let me tell you, a Hi-Fi 3 foot cable can easily cost several thousand dollars. The 40GHz cable would never be enough, as some people can still hear frequencies in that range.
Tsunami -- You can't bring a good wave down!
As I recall, people's hearing tops out at about 25 KILOhertz
Are you kidding? you can't do first post if you RTFA!
The determined Real Programmer can write Fortran programs in any language.

Ahhh, much better.
And now, a PSA from David Lynch.
For the uninitiated, that is Nothing Really Amazing in Outerspace - Alien Life My Ass.
Karma police, arrest this man. He talks in math. He buzzes like a fridge. He's like a detuned radio.
The other thing about terahertz waves is that they behave quasi-optically, being focused by teflon lenses and blocked by cardboard.
So we can finally ditch the tin-foil hats for cardboard hats? About time!
Does it make you happy you're so strange?
I see that his joke was above your head by 39.975 MHz or so.
In Soviet Russia the insensitive clod is YOU!
This is trivial. At Starfleet Academy, surface plasmon polaritons and Fano interference in quasicrystals were on our freshman exams in the first week. Even WESLEY got it right, and he was the dumbest one in our class. Well, except for that guy, George Bush VIII. I don't know how he got in, except his father was like the king of some country named Texas or something. All he ever did was exotic drugs, until the day he blew his testicles off in chem lab. Thank goodness for modern transplant technology.
oh no.. not petahertz... then we'll have those animal rights crazies demanding we let it go..
there are doorways I haven't opened, and windows I've yet to look through. Going forward may not be the answer..
Are you talking about compact discs? because you can hear vinyl way higher than that.
Fascism trolls keeping me up every night. When I starts a preachin', he HITS ME WITH HIS REICH!
All the better if he's dead on, that just saves the rest of us from having to RTFA!
So, CAT-5e is out?
It must have been something you assimilated. . . .
I dunno, apparently many companies are already broadcasting in the 450-750 terahertz range, using something called a "light bulb"...
You know when I put a Cd on my turntable it has no hiss, pops, crackle, clicks, or rumble.
