Victor H. Rumsey

Victor H. Rumsey 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 Victor H. Rumsey rather than just read about it. In short: Victor Henry Rumsey (November 22, 1919 – March 11, 2015) was an electrical engineer, best known for his studies of frequency-independent antennas. Rumsey was born in Devizes, Wiltshire, England, on Saint Cecilia's day, and received his BA in mathematics (1941) and Sc.D. in physics from Cambridge University.

Key takeaways

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

Reference excerpt

Victor Henry Rumsey (November 22, 1919 – March 11, 2015) was an electrical engineer, best known for his studies of frequency-independent antennas. Rumsey was born in Devizes, Wiltshire, England, on Saint Cecilia's day, and received his BA in mathematics (1941) and Sc.D. in physics from Cambridge University. From 1941–1945 he performed radar research at the Telecommunications Research Establishment in England and the Naval Research Laboratory, Washington, D.C. After three years at the Canadian Atomic Research Laboratory he became director of the Antenna Laboratory at Ohio State University. In 1954 he moved to the University of Illinois, in 1957 to the University of California, Berkeley, and in 1966 to the University of California, San Diego where he was a professor and, later, professor emeritus. Starting in the 1950s, Rumsey suggested the basic principles for frequency-independent antennas which culminated in the writing of a book on the topic (see selected works below). Rumsey is a member of the National Academy of Engineering, and has received an honorary Doctor of Engineering degree from Tohoku University, Japan, the 1962 IEEE Morris N. Liebmann Memorial Award, and the 2004 John Kraus Antenna Award.

Worked examples

Example 1 — a first encounter with Victor H. Rumsey

Start with the simplest possible case. Write down what Victor H. Rumsey 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 Victor H. Rumsey 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 Victor H. Rumsey 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 Victor H. Rumsey

In research: Victor H. Rumsey 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 Victor H. Rumsey 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: Victor H. Rumsey is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1919 births, 2015 deaths, American electrical engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Victor H. Rumsey 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.
