  • Means and method for performing shielding effectiveness measurements using mode-stirred chambers
    Patent number: H821
    Abstract: A method of determining radiated shielding effectiveness for a piece of epment under test (EUT) utilizing a mode-stirred chamber. Radio frequency (rf) fields are transmitted from a broad band noise source into the mode-stirred chamber. A first paddle wheel tuner uniformly distributes the rf fields throughout the chamber. The EUT is housed in the chamber such that it is exposed to the transmitted rf fields. A second paddle wheel tuner and receiving antenna are mounted within the EUT to isolate them from the transmitted rf fields. The second paddle wheel uniformly distributes any rf fields that leak into the EUT and the receiving antenna is used to detect the rf leakage.
