Introduction to Electromagnetic Waves: A Comprehensive Guide

As a Doctor of Science in Electrical Engineering from Massachusetts Institute of Technology (MIT), David Hudson Staelin has dedicated his career to educating and consulting on electromagnetic wave phenomena. In this article, we will delve into the fundamental concepts of plane waves, phasors, polarization, energy, power, and force, applying them to problems with progressively more complex boundary conditions.

Electromagnetic waves are a crucial aspect of modern physics and engineering, and understanding their behavior is essential for designing antennas, resonators, and other devices. Staelin's introduction to electromagnetic waves emphasizes concepts, examples, and problem-solving techniques having wide applicability, relying only on basic physics and mathematics.

In this comprehensive guide, we will progress from simple wave propagation in unbounded free space to antenna and resonator design, focusing on generic problem-solving techniques that are both mathematically rigorous and physically intuitive. We will also explore the presentation of basic electromagnetic theorems, such as Poynting's theorem, energy and uniqueness theorems, and reciprocity.

As a renowned expert in his field, Staelin has made significant contributions to the development of patents for grinding and polishing sheet glass, display of dynamic images, and ribbon-beam cathode ray tube. He is also a fellow of the Institute of Electrical and Electronics Engineers (IEEE) and a member of the International Union for Radio Science.

Throughout his career, Staelin has held various academic and consulting positions, including instructor, assistant professor, associate professor, and professor at MIT; consultant to Jet Propulsion Laboratory; director of Environmental Research and Technology, Inc.; visiting assistant scientist at National Radio Astronomy Observatory; and co-founder, chairman of PictureTel Corporation. His expertise has also been sought after as a member of the advisory committee on radio frequency requirements for research, National Academy of Sciences; chairman of the advanced microwave sounder working group, National Aeronautics and Space Administration; and consultant to Lincoln Laboratory.

In conclusion, this article aims to provide an introduction to electromagnetic waves that is both comprehensive and accessible to students and practicing engineers. By applying fundamental concepts to real-world problems, we can better understand the behavior of these complex phenomena and develop innovative solutions for a wide range of applications.
