Faculty and research in Electromagnetics, Fusion and Space Engineering
The programme in Electromagnetics, Fusion and Space Engineering is given by the School of Electrical Engineering and Computer Science at KTH. The field of Electrical Engineering at KTH is currently ranked 23 in the world by QS 2024. Faculty from the Department of Electromagnetic Engineering, Space and Plasma Physics and Fusion Plasma Physics is teaching courses within this programme.
Our anechoic chamber is hosted by the Department in Electromagnetic Engineering. The anechoic chamber is used to characterize antenna, with high accuracy, from 2GHz-70GHz. In the chamber, there are no electromagnetic reflections (or echo), so the radiation pattern and gain of these antennas can be measured as well. In addition to the conventional far-field measurements, our chamber is also equipped with a spherical near-field scanner. The chamber is used for both research and educational purposes. For example, we use the chamber to measure the radiation patterns of cube-sat antennas, or innovative metasurfaces and optically-transformed lenses. The students can do hands-on labs in the chamber, where they measure antennas previously designed by them during the course:

Fusion device: EXTRAP T2R
The Department of Fusion Plasma Physics house a magnetic confinement fusion device named EXTRAP T2R equipped with a digital feedback control system. The EXTRAP T2R device is a medium-sized reversed-field pinch (RFP) located at the Alfvén Laboratory in the Royal Institute of Technology, Stockholm (Sweden). The experiment received EURATOM priority status in 1990 and the first plasma operation occurred in 1994. The front-end of the device was rebuilt in 2000 and equipped with a new resistive shell. This modification has made it possible to study the stability of resistive wall modes (RWM) and to carry out tests of active feedback control of these RWMs. The lab is used in the course:

Inside a major NASA mission
A team from KTH Royal Institute of Technology have created probes for the Magnetospheric Multiscale (MMS) Mission, which sets out to understand the process of reconnection in Earth’s magnetosphere, as well as in the rest of the observable universe.
Hannes Alfvén once said that when he was appointed to the KTH faculty, it meant more to him than what winning the Nobel Prize. As a professor he was exceptionally inspiring and generous, spreading fruitful ideas around.
Europa's peek-a-boo plumes confirmed
The elusive plumes of suspected water vapour shooting out from Jupiter’s moon Europa, first reported in 2013 by Roth at the Department of Space and Plasma Physics, have shown themselves again.
