EMC History and Evolution
The field of electromagnetic compatibility has evolved dramatically since the earliest days of electrical engineering. What began as isolated observations of interference between telegraph lines and early radio systems has grown into a sophisticated discipline essential to modern electronics design. Understanding this history provides valuable context for today's EMC challenges and helps engineers appreciate why certain practices and standards exist.
From the pioneering work of Maxwell and Hertz establishing the theoretical foundations, through the intense development driven by military necessity during World War II, to the explosion of consumer electronics and digital technology in recent decades, EMC has continuously adapted to new challenges. Each technological revolution has brought new interference mechanisms, new susceptibility concerns, and new solutions. By studying this evolution, engineers gain insights that help them anticipate future challenges and develop more robust designs.

About This Category
The EMC History and Evolution category provides essential historical context for understanding modern electromagnetic compatibility. By examining how the field developed over more than a century, engineers gain appreciation for the empirical knowledge embedded in current standards and practices. Many EMC rules that might seem arbitrary make perfect sense when their historical origins are understood. Furthermore, studying past technology transitions helps predict how current trends in areas like high-speed digital, wireless power, and electric vehicles will shape future EMC requirements. This historical perspective transforms EMC from a collection of rules to be memorized into a coherent discipline with clear logical foundations.
