An alternating electric field is applied to ice (530) to generate a resistive AC having a frequency greater than 1000 Hz in interfacial ice at interface (554). A first electrode (510) and a second electrode (514) proximate to the interface are separated by an electrical insulator (512). An AC power source (520) 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.
