  • Electromagnetic surface resistivity determination
    Patent number: 10324048
    Abstract: An apparatus is provided for determining an electromagnetic (EM) characteristic of a material, including a chamber, an antenna, a transmitter, a receiver and a processor. The chamber includes a permanent boundary that encloses a volume; a removable panel along the boundary. The panel includes the material. The antenna is disposed in the chamber for transmitting source EM radiation and receiving reflected EM radiation. The transmitter injects the source EM radiation via the antenna into the chamber. The source EM radiation includes continuous wave (CW) and pulse signals. The receiver obtains reverberated EM radiation from the chamber via the antenna and produces an intermediate frequency signal. The processor controls the transmitter and the receiver. The processor determines a decay time of the EM radiation from the intermediate frequency signal.
