Glen Dash was the author of numerous papers on electromagnetics. He was educated at MIT and was the founder of several companies dedicated to helping companies achieve regulatory compliance. He operated the Glen Dash Foundation, which used ground-penetrating radar to map archaeological sites, principally in Egypt. He died in September of 2019.

Maxwell’s Equations are often introduced as elegant mathematical statements, but their true power lies in what they unlock. In A Dash of Maxwell’s, Glen Dash translates one of the most foundational theories in electromagnetics into a practical, engineer-focused journey from principle to application.

Beginning with the origins of James Clerk Maxwell’s groundbreaking work, this guide walks through the progression from static electric and magnetic fields to the dynamic interactions that drive electromagnetic radiation. What starts as theory quickly becomes insight. Why do structures radiate? How do changing fields propagate energy? And, how can these phenomena be modeled, predicted, and ultimately controlled?

Each chapter builds deliberately:

  • From foundational intuition behind field behavior
  • To the transition between integral and differential forms
  • To computational methods that bring equations into real-world design workflows
  • To applied scenarios, including radiation from a simple wire element
  • To advanced techniques like the Method of Moments, bridging theory and simulation

Rather than treating Maxwell’s Equations as abstract mathematics, this resource positions them as the underlying language of RF engineering. It provides the clarity needed to connect equations to behavior, and behavior to design decisions.

For engineers working in EMC, RF systems, signal integrity, or product design, this is more than a refresher. It is a structured path to understanding the “why” behind electromagnetic phenomena and a practical guide to applying that knowledge with confidence.
