Abstract
An electrode configuration for field cages, especially in microsystems, comprises a large number of electrodes in which an electrical potential can be applied to each end region through a feed region. The end region is arranged to form the field cage and inhomogeneous shielding fields outside the field cage. To reduce thermal convection, the feed region has a strip form whose width is substantially smaller than characteristic dimensions of the end region.
