Radar signatures for drones: Measurement campaign in BiRa test facility
To ensure safe and efficient traffic, the various objects in road and air traffic must be able to quickly detect their spatial environment using radar and communicate with each other via radio networks. In order to investigate the radar reflection of a so-called VTOL drone (short for "Vertical Take-Off and Landing"), which can take off and land vertically without a runway, the Electronic Measurements and Signal Processing (EMS) Group at TU Ilmenau has set up a test facility at the BiRa test facility has just completed an extensive measurement campaign at the BiRa test facility.

Nonadiabatic tunneling is crucial for understanding high harmonic generation from semiconductors
Scientists reveal that nonadiabatic tunneling is crucial for understanding high harmonic generation from semiconductors When matter is exposed to highly intense electromagnetic radiation, nonlinearities of the material may lead to the emission of light that contains very high multiples of the incident frequency.

TU Ilmenau develops bio-inspired microphone for speech recognition
The Technische Universität Ilmenau, together with research partners, has developed a microphone inspired by biology that picks up sound similar to the human ear. The microphone could help improve speech recognition for controlling a variety of digital applications. In the future, the new process could even make overall acoustic systems consisting of a microphone and speech recognition more efficient, so that they consume less energy.

Long-range information transport in antiferromagnets
Antiferromagnets are suitable for transporting spin waves over long distances Smaller, faster, more powerful: The demands on microelectronic devices are high and are constantly increasing. However, if chips, processors and the like are based on electricity, there are limits to miniaturization. Physicists are therefore working on alternative ways of transporting information, such as about spin waves, also called magnons, for example.

New material will make locally flexible diodes possible
Researchers find new material with significant potential for electronics applications Diodes allow directed flows of current. Without them, modern electronics would be inconceivable. Until now, they had to be made out of two materials with different characteristics. A research team at the Technical University of Munich (TUM) has now discovered a material that makes it possible to create a diode with a simple change in temperature.

Bright, stable, and easy to recycle lighting
A low-cost and easy-to-manufacture lighting technology can be made with light-emitting electrochemical cells. Such cells are thin-film electronic and ionic devices that generate light after a low voltage is applied. Researchers at the Technical University of Munich (TUM) and the University of Turin have now used extensive data analysis to create first-class electrochemical cells from copper complexes that emit blue and white light.

Waves on circular paths
Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as "magnons" in analogy to the electron, could transport information much more easily than electrical conductors. An international research team has now made an important discovery on the road to such components, which could be highly energy-efficient and considerably smaller.

TU Ilmenau develops resource-efficient energy distribution network for Germany
In the spirit of the energy transition, TU Ilmenau is developing a resource-efficient power distribution grid for Germany. Such a power grid, based on direct current technology, will be specifically tailored to the increasing use of renewable energy generated in a large number of decentralized plants and will offer significantly higher operational reliability than the current grid.

Programmable Interaction between Quantum Magnets
The forces between particles, atoms, molecules, or even macroscopic objects like magnets are determined by the interactions of nature. For example, two closely lying bar magnets realign themselves under the influence of magnetic forces. A team led by Matthias Weidemüller and Dr Gerhard Zürn at the Center for Quantum Dynamics of Heidelberg University has now succeeded in its aim to change not only the strength but also the nature of the interaction between microscopic quantum magnets, known as spins.

Macroscopic quantum interference in an ultra-pure metal
That visible light holds the character of a wave can be demonstrated in simple optics experiments, or directly witnessed when rainbows appear in the sky. Although the subtle laws of quantum mechanics, that is, wave mechanics, ultimately govern all the processes of electron transportelectrons in solids, their wave-like nature of the electrons is not often apparent to the casual observer.
