Summary: | 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. |
