  • Publication number: 20190018053
    Abstract: An apparatus for relaying microwave field intensity in a microwave cavity. In some embodiments, the apparatus comprises a microwave transparent substrate with at least one Radio Frequency (RF) detector that is capable of detecting a microwave field and generating a signal associated with a field intensity of the detected microwave field and a transmitter that receives the signal associated with the detected microwave field from the RF detector and transmits or stores information about the detected microwave field intensity. In some embodiments, the apparatus relays the microwave intensity via a wired, wireless, or optical transmitter located in proximity of the RF detector.
