In information technology, data transmission rates are constantly increasing, and the need for fast wireless data communication is also growing rapidly. A new approach to communication technology is needed to enable speeds of 100 gigabits per second and higher. The research group "Metrology for THz Communications" with Professor Thomas Kürner (Technische Universität Braunschweig) as speaker is dedicated to this topic. The research group is one of ten new groups established by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) and funded for an initial period of three years. The new alliances will receive a total of around 47 million euros.
At the heart of "Metrology for THz Communications" is communication technology for the largely untouched terahertz frequency range (THz). Terabit per second could be transmitted at this frequency range in the future.
However, compared totoday's communication technology enormous challenges have to be overcome. The DFG is supporting this research with a total of 2.6 million euros over three years.
Professor Thomas Kürner from the Institute for Communications Technology at the TU Braunschweig, designated speaker of the DFG research group:
"The possibility of performing and evaluating precise measurements in the demanding frequency range above 300 GHz with very high bandwidths at the same time is an essential basis for the future development and implementation of THz communication systems. With the research group Meteracom we will be able to make an important contribution to the solution of these challenges".
An essential aspect to achieve the high data rates are the 10s of GHz bandwidths available above 300 GHz. Scientists from TU Braunschweig and the Physikalisch-Technische Bundesanstalt (PTB), the National Metrology Institute of Germany, have been working on THz communication for more than ten years and have also played a leading role in the development of the world's first wireless communication standard for 300 GHz.
The Meteracom research group is doing research on metrology for future THz communication systems and aims, among other things, to design measurement methods that help to predict the performance of THz communication in real environments.
Within the ten sub-projects of the new DFG research group, all aspects of measurement technology are considered, comprising the traceability of measurements to reference standards, the methods for characterizing the measurement systems themselves, the specific measurement methods for characterizing the components of the communication systems and the transmission channel as well as the measurements required for the later operation of the THz-communication systems.
Besides Professor Kürner, two other researchers from TU Braunschweig (Professor Admela Jukan from the Institute of Computer and Network Engineering and Professor Thomas Schneider from the Institute of High Frequency Technology) as well as Dr. Thomas Kleine-Ostmann from PTB are involved.
The competence and the technical equipment available at the Braunschweig location are supplemented by five further researchers from Paderborn, Marburg, Stuttgart, Lübeck and Ilmenau as well as a Mercator Fellow from the National Physics Laboratory, the British counterpart to PTB.
"Metrology for THz Communications" is one of ten new research groups set up by the DFG alongside two clinical and one research group. The new collaborations will receive a total of around 47 million euros. The maximum funding period for these research groups is two three-year periods.
Research groups enable scientists to devote themselves to current and urgent questions in their fields and to establish innovative working directions. In total, the DFG currently funds 153 research groups, eleven clinical research groups and 13 research groups.

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
A research team from the Max Planck Institute for the Structure of Dynamics (MPSD) and the University of Oxford has managed to drive a prototypical antiferromagnet into a new magnetic state using terahertz frequency light. Their groundbreaking method produced an effect orders of magnitude larger than previously achieved, and on ultrafast time scales. The team’s work has just been published in Nature Physics.
Magnetic materials have been a mainstay in computing technology due to their ability to permanently store information in their magnetic state. Current...
