Yahya Rahmat-Samii

Yahya Rahmat-Samii 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 Yahya Rahmat-Samii rather than just read about it. In short: Yahya Rahmat-Samii (Persian: یحیی رحمت-سمیعی; born August 20, 1948) is the Northrop Grumman Chair Professor in Electromagnetics at the electrical engineering department at the University of California, Los Angeles, where he teaches and conducts research on microwave transmission and radio antennas. Rahmat-Samii received his Bachelor of Science degree in electrical engineering in 1970 from the University of Tehran, I…

Key takeaways

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

Reference excerpt

Yahya Rahmat-Samii (Persian: یحیی رحمت-سمیعی; born August 20, 1948) is the Northrop Grumman Chair Professor in Electromagnetics at the electrical engineering department at the University of California, Los Angeles, where he teaches and conducts research on microwave transmission and radio antennas. Rahmat-Samii received his Bachelor of Science degree in electrical engineering in 1970 from the University of Tehran, Iran, and the Master of Science in 1972 and the Doctor of Philosophy degrees in electrical engineering in 1975 from the University of Illinois at Urbana-Champaign. Before joining UCLA in 1989, he was a senior research scientist at the NASA Jet Propulsion Laboratory. He has made innovations in satellite communications antennas, personal communication antennas, wearable and implanted antennas for communications and biotelemetry, and antennas for remote sensing and radio astronomy applications. He is the director of the UCLA Antenna Research, Analysis and Measurement Laboratory.

Worked examples

Example 1 — a first encounter with Yahya Rahmat-Samii

Start with the simplest possible case. Write down what Yahya Rahmat-Samii 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 Yahya Rahmat-Samii 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 Yahya Rahmat-Samii 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 Yahya Rahmat-Samii

In research: Yahya Rahmat-Samii 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 Yahya Rahmat-Samii 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: Yahya Rahmat-Samii is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1948 births, American microwave engineers, American telecommunications engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Yahya Rahmat-Samii 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.
