THz (1 terahertz is a million times million periods a second).
An unused type of radiation known as terahertz radiation was also discussed at the meeting, by David Whittaker from the University of Sheffield .
(sub-millimeter waves or so-called terahertz waves), but applications are now appearing.
Advance made toward communication, computing at 'terahertz' speeds
But physicists have now discovered a way to use a gallium arsenide nanodevice as a signal processor at "terahertz" speeds that could help end the bottleneck.
Physicists in the United States and Germany have discovered a way to use a gallium arsenide nanodevice as a signal processor at "terahertz" speeds, the first time it's been used for this purpose and an important step forward in the new world of optical communication and computing.
The algorithm might now be refined to improve accuracy considerably and an alternative imaging process such as terahertz imaging might also offer more precise data.
T-rays (as the name suggests) have frequencies in the terahertz band (from 300 gigahertz to three terahertz)— also sometimes called the THF (or tremendously high frequency) band.
Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light (400—700 nm), but shorter than that of terahertz radiation (300 gigahertz) and microwaves.
According to a study from Los Alamos National Laboratory, terahertz wave radiation THz emitted by the new scanners creates effects that may interfere with DNA replication.
