Emission Test Method for Source Stirred Reverberation Chambers With Scalar Measurements
IEEE Access, 2023 This paper describes a novel method to reconstruct the radiated emission of a device under test placed in a reverberation chamber equipped with multiple monopole source stirring technique. The method is based on the measurement of the normal component of

Reverberation Chamber Enhanced Backscattering: High-Frequency Effects [PDF]
2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2019 The need for accurate efficiency measurements at high frequencies of large form-factor devices is ever increasing. In this work, the potential of performing antenna efficiency measurements in an electrically extremely large (up to 250λ) reverberation chamber is investigated and compared to its use at lower frequencies.

Employing correlation for wireless components and device characterization in reverberation chambers [PDF]
Journal of Sensors and Sensor Systems, 2019 Reverberation chambers are well-proven test environments for radio frequency (RF) measurements. Typically, mean values are taken from the measurements to characterize the equipment under test.

IEEE Open Journal of Antennas and Propagation, 2023 We extend the autocorrelation-based approaches currently used in standards to full correlation-matrix-based approaches in order to identify correlation between both spatially adjacent and non-adjacent samples in reverberation-chamber measurements.

Radiated Immunity Testing of a Device with an External Wire: Repeatibility of Reverberation Chamber Results and Correlation with Anechoic Chamber Results [PDF]
, 2003 We present the experimental radiated immunity results of an electronic device with an external wire obtained in reverberation and anechoic chambers. Repeatability and reproducibility of reverberation chamber measurements are investigated by repeating the

Reverberating chamber profile identification
IET Microwaves, Antennas & Propagation, 2012 This study proposes a model, based on the generalised K (GK) distribution, for identifying the reverberating chamber (RC) propagation channel profiles. Following this rationale, a parameter, given by a proper combination of GK parameters, is not only able to clearly distinguish between line-of-sight (LOS) and non-line-of-sight conditions, but it is ...

Measurement of Absorption Cross Section of a Lossy Object in Reverberation Chamber Without the Need for Calibration [PDF]
, 2016 A reliable and simple procedure is proposed to measure the averaged absorption cross section (ACS) of a lossy object in a reverberation chamber (RC). This procedure is based on the time-domain measurement of the ACS in an RC.
