abstract = "The potential generated in a set of concentric ring electrodes by a moving dipole layer was simulated by a linear finite element model. The wavefront was represented by rectangular charged elements with the charge concentrated at the center of each element. The model was refined to reflect the solid angle described by the corners of the finite element and the center of the element on the ring of interest. This corrects the potential while the dipole layer is near the center of the sensing electrodes. The model confirms that the far-field dependence of both bipolar and tripolar rings is a function of r-4, where r is the radius of the ring. As expected, the tripolar configuration is more spatially sensitive with a smaller amplitude. When signal amplitude is more important than spatial specificity then the bipolar configuration appears superior.",
