Abstract
Dielectric heating is used to cause explosive nucleation of ink in an ink reservoir to expel a drop of ink from an inkjet print head. Conductive plates generate an alternating electric field at microwave frequencies across an ink reservoir causing the ink to heat. Since the ink is heated without heating the conductive plates, less heat dissipation of the inkjet print head is necessary.
