To enable high-speed wireless communications and to spot hidden explosives and chemical or biological weapons researchers from University of Utah has finally discovered the possibility to attach far infrared light or terahertz electromagnetic radiation on metal foils punctured with holes.
This whole arrangement is also known as quasi crystal and quasi crystal approximate patterns. The new pattern facilitates almost all the radiation to pass through the metal foils even when the holes are made only on a small portion of each foil’s surface.
Till now, efficient transmission of far-infrared light was achieved with the help of crystal patterns. Now, to avoid unwanted frequencies transmitted by crystal patterns researchers in their new study could select the wavelength of far-infrared light transmitted through the holes and by tilting the films they could switch the transmission on or off to transfer data in the digital code of one and zeroes.
This remarkable discovery reveals that day is not far when high-speed switches will be build to transmit terahertz data at terahertz speeds that will be 10,000 times faster than microwaves that transmits cordless and cell phone conversations.
