The behavior of the electromagnetic field at edges of media with finite conductivity

The principal behavior of both electric and magnetic fields at the edges of media with finite conductivity is investigated. The authors find that, as in the case of ideal conductors, the normal electric field shows a singularity at the edge. The energetic field components, however, remain bounded if...

Zusammenfassung:The principal behavior of both electric and magnetic fields at the edges of media with finite conductivity is investigated. The authors find that, as in the case of ideal conductors, the normal electric field shows a singularity at the edge. The energetic field components, however, remain bounded if the permeabilities of the neighboring media do not differ. Detailed results on typical geometries are given.< >
