Abstract

It has been shown that the voltage measured by an electrode pair due to a dipole is the dot product of the Lead Field and the dipole vector. When the surfacc of an electrode is roughened, the surface current dciisity becomes irregular and the Lead Field is altered accordingly. In this paper, we introduce a 2-dimensional Boundary Element Model to compute the Lead Field between two parallel plate electrodes and illustrate how surface roughness alters the potential measurements from
a unit dipole. The results indicate potential measurements are only offsct if the dipole is located in a boundary layer with a thickness twice thc depth of the surface texture.
