Abstract
An apparatus for applying electromagnetic energy to a dielectric fluid includes a chamber to contain the dielectric fluid. At least three parallel or coaxial electrode plates are arranged within the chamber to apply substantially equal electromagnetic energy per unit volume of the dielectric fluid between neighboring ones of the at least three electrode plates. Electrical conductors are electrically connected to electrode plates to apply a radio frequency electric field between neighboring ones of the at least three electrode plates. In one embodiment the electrode are connected in series and in another embodiment the electrodes are connected in parallel.
