Abstract
Disclosed are methods and apparatuses for heating an object in a cavity by feeding the cavity with RF signals. One of the disclosed methods includes simultaneously feeding the cavity with at least two RF signals. Of the at least two RF signals, a first RF signal is fed to the cavity via a first antenna and a second RF signal is fed to the cavity via a second antenna. The first and second RF signals have a common frequency and differ in phase by a first phase difference. The method also includes measuring the first phase difference and adjusting the feeding based on measurements of reflected RF signals reflected from the cavity. Conducting the measurements of the reflected RF signals may also be part of the disclosed method. A disclosed apparatus includes the structure required for carrying out the above method.
