Abstract
This chapter addresses the issue of associating the location and nature of the electric field sources below the surface of a conductive medium with the corresponding potential distribution on that surface. Single-point sources (monopoles), pairs of opposite sources (dipoles), and pairs of dipoles (tripoles or quadrupoles) are investigated together with the detection modalities of the surface potential (monopolar, differential, etc.). The electric potentials generated by sources moving under these detection systems are described using a qualitative approach. The general concept of a spatial filter is introduced.
