Birthday edition of the RWTH Science Night ‘5 to 12’
The magnetic globe rotates weightlessly on its own axis – just like in outer space
For the 20th time, RWTH Aachen University offered a glimpse behind the scenes. This time, 7,200 visitors, including many children, came to the C.A.R.L. auditorium between 6 p.m. and midnight to experience the world of research at close quarters.
What started out as a modest idea to present science at an unusual time, in an entertaining way and free of charge to anyone interested, has grown over the past 20 years into a mega-event that not only attracts thousands of guests, but also inspires the members of the university involved. Once again, the team of the Faculty of Electrical Engineering and Information Technology welcomed curious children of all ages and were on hand to help them with experiments.
With questions such as “Why isn’t the light on now?”, “How does that work?” or “Can I do one more experiment?” younger children followed their natural urge to discover new things.
The programme included reconstructing electrical circuits where they could visualise electric current as light or movement. They made switches, explored the magnetic and thermal effects of electricity, learned to distinguish between conductors and non-conductors, and finally became familiar with electricity.
Faculty members provide support when experimenting with electric circuits
Older children ‘already had this at school’ and enjoyed putting their theoretical knowledge to the test. But adults also found their way to our station, taking the opportunity to generate lightning with the influencing machine, thoughtfully lingering in front of the floating globe, or attentively studying the model of the power distribution network set up by the Chair of Automation of Complex Power Systems. The joy of experiencing research and progress together is clearly at the centre of the Science Night.
„We want to show in an entertaining way what RWTH has to offer – and in such a way that everyone who wants to know something can understand it,’ said Rector Ulrich Rüdiger.
The potential of the Science Night is therefore even greater, as it represents an important interface where the direct transfer of knowledge takes place in a social and cultural context. In line with the motto ‘from the laboratories to the people’, it makes an important contribution to promoting proximity between science and society.
The station of the Faculty of Electrical Engineering and Information Technology, equipped with numerous child-friendly experiments
The programme for this year’s Science Night took place in ten lecture halls and numerous seminar rooms. There were over 80 shows and lectures, experiments, talks and discussions. From Artificial Intelligence (the experts from the RWTH’s AI Centre had brought along the robot ‘Pepper’ for support) to the ‘Physics Fair’, from the latest information on the US elections and the spectacular ‘Fascination of High Voltage’ to the circular economy, floating Teslas and the construction site of the future. The range of topics was as colourful and diverse as the RWTH itself.

A look at the team from the chair of Transmission Grids and Energy Economics at the Institute of High Voltage Equipment and Grids, Digitalization and Energy Economics (IAEW) presents a pleasing picture for the field of electrical engineering: almost a third of its researchers are female.
The share of women in engineering has increased in recent years, and female engineers are a natural part of an institute team. All of the female researchers in the team have completed a degree in the field of electrical engineering and then decided to complete a doctorate at the university and start their professional career here. Of course, working in electrical engineering requires a certain interest in science and technology, but the key to success and fun is usually the curiosity to understand new things.
We are always motivated by the question: ‘How does this work?’, says Lina Fischer, who is researching a robust planning model for the future energy system.
The next step is simply to have the bravery to actively pursue these questions – even if it means venturing into the unknown.

Everyone at the IAEW is driven by the vision of researching and developing solutions for the energy transition. The work at the chair of Transmission Grids and Energy Economics is primarily focusing the question:
„How should we design the future energy system so that it is environmentally friendly, reliable and economically efficient?“
This covers a wide range of interesting aspects. For example, lot of research is done on how the large amounts of energy from photovoltaic and wind energy plants, as well as alternative energy sources such as hydrogen, can be integrated into the current energy system. The transmission grid for electricity is essential for this. It can be seen in everyday life, for example, by the high-voltage power lines running alongside the freeways. The transmission grid enables electricity transport over long distances and thus the transport of large amounts of energy from wind turbines in northern Germany to regions with high electricity consumption. Current projects at the chair are investigating how the transmission grid needs to be expanded and operated in the future in order to facilitate the energy transition. Research is also ongoing in determining the locations where power lines to offshore wind turbines in the North and Baltic Seas should be connected to the grid or where large electrolysis plants for the production of hydrogen should be positioned. In addition to the technical aspects of the components, these studies must also take economic aspects into account, such as the costs arising from investments or possible congestions in the transmission grid.
In general, the consideration of economic and market aspects plays a major role in the transformation of the energy system. European efforts to further strengthen electricity trading between the individual countries are leading to increasing electricity exchanges in Europe and thus to further challenges for the transmission grid. The chair is therefore developing methods and models to simulate the European electricity markets. In this way, various future developments can be examined and their potential impact on market participants and the transmission grid can be analyzed.
A further focus of the chair is to deal with innovative concepts that will ensure the secure and reliable operation of transmission grids in the future and thus protect against blackouts. To this end, models and processes must be developed that can represent and investigate the dynamic system behavior of transmission grids and their components under changing conditions.

When you think of working at a university institute, your first thoughts usually revolve around working solely on your own research project. This often gives a false impression of work life at an institute, especially in the field of engineering. Work at the IAEW is characterized above all by the variety of different projects with both research and industrial partners. This allows you to get to know different topics and to gain a wide range of experience. You are often involved from the very beginning of the projects through working on them on to the presentation of the results. The different project teams make the collaboration very varied. In addition to scientific knowledge, your time at the institute gives you the opportunity to acquire a range of skills that qualify you for management positions in the industry.
Of course, you also experience many other things that make working at the institute worthwhile.
“In particular, the joint activities with other young colleagues after work, various institute traditions, parties and sporting events are all part of it.”
Notably, the IAEW also offers the opportunity to gain insight into the institute and its research topics through student assistant jobs or a thesis.

School’s out! – What next?

Which study programme is right for me? And what will my working life look like?
During the orientation phase, we develop a first picture of our future professional life. This image is shaped by various influences, usually from our immediate environment: What are my parents’ professions? What did my teacher advise me to study? But as individual as we are, the possibilities are just as varied – and the more often we take the opportunity to gain an insight into different professions, the wider our field of vision becomes and the clearer our personal path appears.
The researchers at the Institute for High Voltage Equipment and Grids, Digitalization and Energy Economics (IAEW) at RWTH Aachen University share their professional and personal experiences in three articles. The scientists, each team work in one of the institute’s three chairs, have different research focuses. However, they all have one goal in common: to integrate their ideas into people’s lives and thus advance our society.
Among other things, they address the following questions:
- How can large amounts of energy from photovoltaic and wind power plants be integrated into our electricity system in the future?
- What challenges will arise from the increasing share of renewable energies and flexible consumers such as heat pumps and electric cars?
- What is necessary to ensure a reliable energy supply and to avoid blackouts?
What else will the scientists share with you:
- How do typical researchers think? Do they work alone on their own research projects?
- What are the career prospects after a PhD? Do science and business exclude each other?
- When did the desire to become an electrical engineer arise, what is a typical working day like and what role does work-life balance play?

Welcome to my work – Interview with Rebecca Rodrigo
Fast, faster, the speed of light – a characteristic of modern data communication and the reason why a physicist found her way into the electrical engineering world.
Rebecca is a physicist and has been working as a cleanroom engineer at the Institute of Integrated Photonics at RWTH Aachen University since 2020. Here she gives an exclusive insight into her everyday working life.
Career guidance is often a challenge for school students. Rebecca, how did you find your way?
“Even in primary school I was very interested and enthusiastic about STEM subjects. Thanks to a dedicated and motivated physics teacher at secondary school, I decided to study physics instead of maths and physics as a teacher. I wanted to keep my options open for the future. I ‘fell in love’ with research during my bachelor’s thesis and have stayed with it ever since.”
Photonics is the technical mastery of light, which has many fascinating properties. What is photonic-electronic integration?
“Most people are familiar with electronic microchips. Integrated photonics is now concerned with implementing these functionalities on photonic microchips, where photonic signals are carried, manipulated and measured instead of electrical signals. The two microchips can also be combined or integrated to take advantage of the best features of both technologies.”
A personnel airlock leads into the cleanroom. Rebecca wears abrasion-resistant clothing to protect the ultra-sensitive microchips.
The cleanroom provides a controlled environment for specialised manufacturing processes such as the production of photonic integrated circuits on computer chips. What conditions are required in the cleanroom and why?
“The extremely low-particle environment is obviously very important, because even the smallest dust particle that gets on a microchip during the manufacturing process can affect its functionality. In our cleanroom, for example, we have only 100,000 particles larger than 0.1 micrometres per cubic metre, compared to 150 to 1000 times more in normal ambient air. The relative humidity and temperature in the cleanroom are also strictly monitored and kept constant, as the chip manufacturing processes are very sensitive.”
Rebecca works on the die-bonder using flip-chip technology: for chips to work properly, they need to be assembled and interconnected. The design and manufacture of these connections is known as packaging.
Photonic-electronic integration is a key technology for digitalisation. It meets the challenge of transporting and processing more and more data as we move towards a new information society. How exactly does this technology contribute to the solution?
“Most people are familiar with fibre optic technology from everyday life. Its advantages in data transmission lie primarily in its speed, but also in its energy efficiency compared to copper technology. We use the same principle, just miniaturised on a chip. It is no longer called fibre optics, but waveguides – but the basic principle is the same!
The advantage of photonics in data communications, whether over long distances as fibre-optic cables or miniaturised in chips for data centres, is therefore speed: we are unlikely to go faster than the speed of light in the foreseeable future. Parallelisation is also a clear advantage: different signals can be transmitted in parallel at different wavelengths or polarisations.”
What groundbreaking developments is the Institute of Integrated Photonics involved in? Which projects are you especially excited about?
“We have a lot of exciting projects and my role has the advantage that I am basically involved in all of them. There are certainly two projects that are particularly exciting in terms of these future technologies.
In the ML4Q cluster, we are involved in the development of a quantum computer. Many people are probably aware of the importance of this technology, for example in the field of quantum cryptography and supercomputing. Our specific task in this project is to realise a highly efficient photonic interface between spin qubits.
In the NeuroSys cluster, the IPH is working on a physical neural network based on photonic neurons. It is therefore a photonic AI. However, due to the size of such neural networks integrated on chips, it is not so much an AI like Chat GPT, but rather highly specialised and trained networks that score points in data centres for their enormous speed.”
Rebecca’s office is a space for dynamic workflows and creative ideas.
What is your typical working day like?
“On a day-to-day basis, I sometimes work very application-oriented directly in chip production on the systems and also train other employees in the application. At the same time, a large part of my work consists of designing new production processes, advising my colleagues as an expert in clean room technology, scientific research and coordinating a lot of maintenance work, for example. I also have management responsibility for my small cleanroom team, which consists of one permanent employee and several students. Supervision of final theses is also part of my job.”
What does work-life balance mean to you?
“Work-life balance is very important to me. For me personally, it is really about balance. Last autumn, I had the privilege of becoming a mother to a beautiful little girl who is, of course, my world. Together with my partner, we have decided to share caring and paid work 50:50. For me, this is the perfect solution and the best of both worlds: playing and exploring with my daughter is great fun and keeps me grounded, while my job helps me to get out of the baby bubble and focus on intellectual issues.”

On 14 June 2024, the Institute of Communication Systems (IKS) celebrated its 60th anniversary.
This anniversary was celebrated together with project partners, colleagues and numerous alumni in a festive colloquium and evening event. The event provided an insight into the development of digital speech and audio communication. It was also an opportunity to look back over the past six decades and to discuss future challenges and opportunities in the field of communication systems.
“We would like to thank everyone who has supported the Institute over the past 60 years and look forward to many more successful years,” the IKS announced.
Professor Jax has led the Institute since 2015. He initiated a new name and a research focus on modern digital communication systems. Research continues to focus on speech and audio communication as probably the most important and natural link between us humans. The research deals with signal processing in communication systems, e.g. in hearing aids, hearables or immersive 3D telephony. The aim is to make digital communication systems as natural as “direct” face-to-face speech communication. Both model-based digital signal processing and machine learning methods are used in innovative hybrid solutions.

One of the highlights of the event was the formal appointment of Marc Adrat as Honorary Professor. He is an internationally recognized expert in the field of Software Defined Radio, which involves programmable digital radio systems where essential transmission functions such as coding, error correction, modulation, and synchronization are implemented via software. His teaching activities focus on modern error-correcting channel coding in the course „Modern Channel Coding for Wireless Communications“, which is offered as part of the regular „Master’s programme in Electrical Engineering and Information Technology“.
“His expertise and commitment will undoubtedly continue to have a significant impact on the quality of our teaching and research,” stated the IKS.
The appointment will also strengthen the collaboration between the Faculty of Electrical Engineering and Information Technology and the Fraunhofer Institute for Communication, Information Processing and Ergonomics.
