Control of a pulsed coplanar discharge by two-dimensional potential tailoring is investigated experimentally in a flat tetrode configuration. One pair of electrodes generates a coplanar discharge, and the other electrodes play roles of switching and controlling the discharge current by changing their electrical potential, where their electrical isolation from the discharge channel is kept without an insulator layer. All the electrodes are cold and arranged on a completely flat plate immersed in discharge gas with the pressure which is in the region to the right of and near the minimum sparking voltage condition.
