Course details

This course helps students understand how electromagnetic waves travel in different media such as wires, waveguides, optical fibers, and free space. It starts with guided wave propagation in transmission lines and metallic waveguides used in RF and microwave systems. The course then explains how light propagates in optical waveguides and optical fibers, which form the backbone of modern communication networks. Free-space wave propagation is also discussed to connect theory with wireless communication systems. In the later part, students are introduced to the basic working principles of antennas and how they radiate electromagnetic energy. Simple antenna models and wireless channel concepts are explained to build intuition. The course connects mathematical concepts with real engineering applications. Emphasis is given to understanding physical meaning rather than only formulas. Assignments include conceptual questions to strengthen fundamentals and computational problems to build problem-solving skills. By the end of the course, students gain a strong foundation in electromagnetic wave propagation across wired and wireless systems.

Questions and Answers

Q: You're signing off an EMC test plan for a 24 GHz short‑range radar. The supplier argues to relax chamber absorber layout because vehicle testing already passed CISPR 25. You're searching "ISO 11452 reverberation chamber field uniformity requirement automotive". Why does ISO 11452 insist on field uniformity verification in a reverberation chamber instead of relying on total input power?

Q: A guided microwave link at 5.8 GHz shows intermittent dropouts only during cold soak at −30 °C. VSWR spikes from 1.3 to 2.8, then recovers warm. You're googling "waveguide intermittent VSWR cold temperature failure". What's the root cause that fits all symptoms?

Q: You're reviewing an antenna datasheet callout on a GA drawing. The note says "50 Ω feed, SMA‑K, DC grounded". The subcontractor added an inline bias‑tee anyway. You're searching "DC grounded RF antenna SMA datasheet meaning". What did they misread?

Q: An outdoor X‑band waveguide run sits 200 m from a coastal road, −10 °C to +45 °C, no purge. After 18 months insertion loss creeps up. You're searching "aluminum waveguide corrosion coastal environment". What's the dominant degradation mechanism?
