Ilona Rolfes

Ilona Rolfes is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ilona Rolfes rather than just read about it. In short: Ilona Rolfes (born 1973) is a German microwave engineer who studies devices for generating and measuring terahertz radiation and their applications including in health technology, environmental modeling, and short-range radar imaging systems for vehicles. She is a professor at Ruhr University Bochum.

Key takeaways

Ilona Rolfes belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ilona Rolfes to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ilona Rolfes from memory before moving on to harder problems.

Reference excerpt

Ilona Rolfes (born 1973) is a German microwave engineer who studies devices for generating and measuring terahertz radiation and their applications including in health technology, environmental modeling, and short-range radar imaging systems for vehicles. She is a professor at Ruhr University Bochum.

Education and career Rolfes was born in Hagen in 1973. She became a student of electrical engineering at Ruhr University Bochum, where she received a diploma (the German equivalent of a master's degree) in 1997, and completed a doctorate in 2002. After continued postdoctoral research at Ruhr University Bochum, she became a junior professor of electrical engineering at Leibniz University Hannover from 2005 to 2009 and director of the Institute for Radiofrequency and Microwave Engineering from 2006 to 2009. She returned to Ruhr University Bochum as a professor and chair of Microwave Systems in 2010.

Recognition Rolfes received the European Microwave Prize in 2001 and the outstanding young engineer award of the IEEE Microwave Theory & Technology Society in 2011. She was elected to acatech, the German Academy of Science and Engineering, in 2015, and to the North Rhine-Westphalian Academy of Sciences, Humanities and the Arts in 2023.

Worked examples

Example 1 — a first encounter with Ilona Rolfes

Start with the simplest possible case. Write down what Ilona Rolfes claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ilona Rolfes before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ilona Rolfes ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ilona Rolfes

In research: Ilona Rolfes appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ilona Rolfes in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ilona Rolfes is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1973 births, Academic staff of Leibniz University Hannover, Academic staff of Ruhr University Bochum, so understanding it makes those chapters shorter.
In everyday life: Look for Ilona Rolfes outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
