Abstract
An alternating electric field is applied to ice () to generate a resistive AC having a frequency greater than 1000 Hz in interfacial ice at interface (). A first electrode () and a second electrode () proximate to the interface are separated by an electrical insulator (). An AC power source () provides a voltage of about 10 to 500 volts across the electrodes to create the alternating electric field. A portion of the capacitive AC associated with the alternating electric field is present in the interfacial ice as conductivity (resistive) AC, which causes dielectric loss heating in the interfacial ice.
