An apparatus for forming an electromagnetic field in a processing chamber, including a first pair of electrodes for generating a first electromagnetic field within the processing chamber and a second pair of electrodes for generating a second electromagnetic field within the processing chamber. The first and second pairs of electrodes are oriented so that the first and second electromagnetic fields are oriented generally perpendicular to each other. When energized, the first and second electromagnetic fields combine and may take the form of a lissajous pattern. When a gas is exposed to the combined electromagnetic field a plasma may be formed in the general shape of the combined electromagnetic field.
