Researchers have created a unique device which will unlock the Elusive Terahertz Wavelengths and Make Revolutionary New Technologies possible.
Terahertz Waves (Thz) Sit Between Microwaves and Infrared in the Light Frequency Spectrum, but to their low-energy scientists have been unable to harness their potential.
The conundrum is known in Scientific Circles as theterahertz gap.
Being Able to Detect and Amplify Thz Waves (T-Rays) Would Open Up a New Era of Medical, Communications, Satellite, Cosmological and Other Technologies.
One of the Biggest Applications Would Be AS A SAFE, non-destructive alternative to x-rays.
However, UNTIL NOW, The Wavelengths - Which Range Between 3mm and 30µm - Have proven impossible to use due to relatively weak signals from all existing sources.
A Team of Physicists has created a New Type of Optical Transistor-A Working Thz Amplifier-Using Graphene and A High-Temputure Semiconductor.
The Physics Behind the Simple Amplifier Replicé On the Properties of Graphine, which is transparent and is not sensitive to light and whose electrons have no mass.
It is made up of Two Layers of Graphene and A Superconductor, Which Trap the Graphine Massless Electrons Between them, likewich.
The Device is then connected to a power source.
When the Thz Radiation Hits The Graphine Outer Layer, The Trapped Particles Inside Attach Themselves to the Outgoing Waves Giving Them More Power and Energy Than They Arrive With - Amplifying Them.
Professor Fedor Kusmartsev, of Loughborough's Department of Physics, Said: “The Device has a very simple structure, consisting of Two Layers of Graphne and Superconductor, Forming A Sandwich (as Shown Above).
“ As the Thz Light Falls on Sandwich It Is Reflected, Like Mirror.
“The main point is that there will be more light reflecting Than Fell on the Device.
“ It Works Because External Energy is supplied by a battery or by light that hits the surface from Other Higher Frequencies in the electromagnetic spectrum.
“The thz photons are transformed by the graphene into massless electrons, which, in turn, are transformed back into reflect, energy, thz photons.
“ Due to such a transformation the thz photons Take Energy from the graphne - or from the battery - and the weak thz signals are amplified.
The Breakthrough - Made by Researchers from Loughborough University, in the UK; Been Published in Physical Review Letters ("Optical Transistor for an Amplication of Radiation in A Broadband Thz Domain
" )
. Added that such a Device would vastly improve Current Technology and Allow Scientists to Reveal More About the Human Brain.
“The universe is full of terahertz radiation and signals, in fact, all biological organizations Both absorb and emit it.
“ I hop, that with such an amplifier avairable we will be able to discover many mysteries of nature, for example, How Chemical Reactions and Biological Processes Are Going On Or how to work. Think.
“The Terahertz Range is the last frequency of radiation to be adopted by humankind.
“ Microwaves, infrared, visible, x-rays and other bandwidths are vital for counteless scientific and technological advancements.
“It has properies that would greatly improve vast areas of science such as imaging, spectroscopy, tomography, medical diagnosis, health monitoring, environmental control and bay and biological identification.
“ The device we have developed will allow scientists and engineers to harness the illustive bandwidth and Generation of Medical Equipment, Hardware and Wireless Communication Technology. ”
