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."
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!
Are you kidding? you can't do first post if you RTFA!
The determined Real Programmer can write Fortran programs in any language.
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!
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!
I dunno, apparently many companies are already broadcasting in the 450-750 terahertz range, using something called a "light bulb"...
