Abstract
We propose a finite-element scheme which involves the use of the Lagrangian interface technique to model electromagnetic signal propagation in mixed regions of very low and high conductivity. The method has relevance to modeling underground communications in oil or gas wells. There will be a significant jump in electrical conductivity especially at the interface between the iron and the nonmetallic conductive regions
