Thermal Noise Measurements in a Reverberation Chamber
IEEE transactions on electromagnetic compatibility (Print), 2022 Two modelsdescribing properties of the thermal noise power emerging from an antennamounted in a reverberation chamber are described. The first compares the reverberation chamber to an over-molded cavity acting as a black-body source; the second describes
