APPARATUS AND METHOD FOR SENSING AND PROCESSING BY RF

摘要

A disclosed apparatus for sensing and processing an object in a cavity (104) comprises a sensing RF source (110) and a sensing antenna (112), and a processing RF source (120) and a processing antenna (122). The sensing RF source is configured to generate low power RF radiation at a first frequency range and the sensing antenna is configured to feed the cavity with RF radiation generated by the low power RF source. The processing RF source is configured to generate high power RF radiation at a second frequency range, and the processing antenna is configured to feed the cavity with RF radiation generated by the processing RF source. A protecting system (130) configured to protect the sensing RF source from RF radiation generated by the processing RF source may be provided.
