Abstract

A method includes processing an object in a cavity by applying radio frequency (RF) energy to the cavity. A first plurality of frequencies is identified, characterized in that a time derivative of a value indicative of a dielectric response of the cavity to RF energy at frequency of the first plurality of frequencies is larger than a first threshold. More energy is applied at frequencies of the first plurality of frequencies than at other frequencies.
