The Conducting Core

  • Neil R. SheeleyJr.


Here, we consider what happens when the current in a unit sphere is turned on suddenly while a smaller perfectly conducting sphere of radius 𝜖 is centered inside. As in the case without the central core, two waves will leave the current source, one heading outward away from the sphere and the other heading inward toward the center. If the core were not present, the incoming wave would turn around when it reached the center and then move back out through the sphere to form the trailing edge of an outgoing bubble of thickness 2R (where R = 1 for the unit sphere).
