This article uses a classical circuit-theory model of a series RLC circuit to explain the phenomenon of ringing on a transmission line, or a PCB trace.
Protection from high-altitude electromagnetic pulse (HEMP) and intentional electromagnetic interference (IEMI) is an important consideration to the design of modern electronic systems, especially those that control critical infrastructures.
The evolution of E and H fields on aircraft struck by lightning is a complex process. An October 2014 in-flight lightning strike is reviewed in this article as an example that inspires a fresh look at how lightning E and H fields should be considered for indirect effects certification.
