Claim:
1. A method for evenly heating a treatment region of a subject via the application of an alternating electric field, comprising: positioning a treatment region of a subject between a first high voltage electrode and a second ground electrode, wherein said first electrode is parallel to said second electrode, wherein said treatment region has a plurality of thicknesses extending between said first and second electrodes, wherein said first and second electrodes are connected to a generator operable to apply an alternating electric field between said electrodes; calculating a dielectric constant and a dissipation factor for a material that enables a substantially constant current to pass between said first and second electrodes and through said thicknesses of said treatment region and said material upon application of said alternating electric field, wherein said substantially constant current comprises a current in which a difference between a first current passing through said treatment region compared to each other current passing through said treatment region is less than ±25%; displacing any air located between said treatment region and said first and second electrodes with at least one flowable material, wherein said flowable material is made of a composition having said calculated dielectric constant and dissipation factor; and activating said generator to apply said alternating electric field such that said substantially constant current passes between said first and second electrodes and through said treatment region and said flowable material to thereby heat said treatment region across the thicknesses thereof.
