Abstract
The computation of the lead field of a plane bipolar electrode with axial symmetry is discussed. The numerical technique used is based on an analogy of the ‘charge density method’. An explicit analytical formula describing the potential arising from a plane annulus having uniform (current) density is presented. A verification of the technique is given by comparing the results with both a known analytical expression describing the field of a disc electrode and measurements inside a tank. The lead field is computed for several values of the radii involved and is shown to posses a pronounced directional sensitivity. Possible applications are discussed.
