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.

Long-range information transport in antiferromagnets
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.
