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.

Abstract: An apparatus for applying RF energy to process an object may include at least one controller configured to receive EM feedback-related values from an energy application zone, each of the values being associated with a respective MSE. The controller may also be configured to identify a change in one or more of the EM feedback-related values within a period of time; adjust the RF energy application based on the change in the EM feedback-related values identified, and cause application of RF energy to the energy application zone.

Abstract: An object is processed in a cavity resonator by application of radiofrequency energy to the cavity resonator through a plurality of feeds. Excitation setups are grouped into a plurality of peaks based on values of an absorbability indicator associated with each of the excitation setups. At least one peak among the plurality of peaks is selected based on the values of the absorbability indicator associated with the excitation setups grouped into each peak. Radiofrequency energy is applied to the cavity resonator based on the selection, in which the excitation setups are multi-dimensional.

Abstract: Methods and apparatuses for processing objects by RF energy are disclosed. In some embodiments the method may include grouping excitation setups into at least a first group corresponding to a first peak and a second group corresponding to a second peak. The method may further include applying RF energy such that an amount of RF energy absorbed at excitation setups of the first group is equal to an amount of RF energy absorbed at excitation setups of the second group. Apparatuses according to some embodiments may include a processor configured to carry out aspects of the method.
