New wireless phones transmit at ultra-fast speed

01.04.2004


Researchers in Germany claim to have opened the door to a new form of wireless communication by transmitting information at "terahertz" frequencies for the first time. The work could eventually lead to mobile phones that can transmit greater amounts of information at faster speeds than conventional devices, which use lower frequency microwaves. The team, led by Martin Koch from the Technical University of Braunschweig, encoded the electrical output from an audio CD player onto a terahertz beam and sent it over a distance of almost a metre.



The signal was then picked up by an antenna and forwarded to a loudspeaker. The first piece of music they transmitted and listened to was Billy Joel’s We Didn’t Start the Fire. Meanwhile, Giles Davies from Leeds University examines other applications of terahertz radiation, including how it can be used to spot terrorist threats, such as concealed weapons, explosives and biological agents like anthrax.

Im Focus: Goodbye, silicon? On the way to new electronic materials with metal-organic networks

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.

Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

Im Focus: Storage & Transport of highly volatile Gases made safer & cheaper by the use of “Kinetic Trapping"

Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles

Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...

Im Focus: Disrupting crystalline order to restore superfluidity

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.

We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
