Abstract: An apparatus for applying electromagnetic energy to an object in an energy application zone via at least one radiating element is disclosed. The apparatus may include at least one processor. The at least one processor may be configured to determine a value indicative of energy absorbable by the object at each of a plurality of frequencies and to cause the at least one radiating element to apply energy to the zone in at least a subset of the plurality of frequencies. Energy applied to the zone at each of the subset of frequencies may be a function of the absorbable energy value at each frequency.

Abstract: Apparatus and method for applying RF energy to determine a processing state of an object placed in a cavity, during processing of the object. The method includes applying RF energy to the object during the processing via at least one radiating element, receiving RF feedback from in or around the cavity, said RF feedback being indicative of a dielectric response of the cavity and/or the object to electromagnetic (EM) fields excited in the cavity, mathematically manipulating the RF feedback to obtain computed RF feedback, determining one or more processing states of the object based on a correlation between the computed RF feedback and the one or more processing states of the object, and monitoring the computed RF feedback during the applying to monitor the one or more processing states of the object.

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.
