Abstract
A method of heating and/or thawing using an RF heater is described. In some cases the heating differentially heats portions according to their dissipation ratios. Optionally, this avoids dissipating large amounts of energy into thawed portions while frozen portions are still extant and heat slowly. Optionally, this prevents overheating of thawed portions.
