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.

Small-sized reverberation chamber for the measurement of sound absorption
Materiales de Construccion, 2017 This paper presents the design, construction, calibration and automation of a reverberation chamber for small samples. A balance has been sought between reducing sample size, to reduce the manufacturing costs of materials, and finding the appropriate ...

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 ...

Spatial Resolution of Late Reverberation in Virtual Acoustic Environments
Trends in Hearing, 2021 Late reverberation involves the superposition of many sound reflections, approaching the properties of a diffuse sound field. Since the spatially resolved perception of individual late reflections is impossible, simplifications can potentially be made ...

FDTD modelling of reverberation chamber
Electronics Letters, 2005 The finite-difference time-domain (FDTD) method is applied to the simulation of a reverberation chamber. The real losses of the reverberation chamber are taken into account in a post-treatment process. The predicted results are compared with measured data and good agreement is reported.

Spatial Correlation and Ergodic Capacity of MIMO Channel in Reverberation Chamber
International Journal of Antennas and Propagation, 2012 It has previously been shown that a reverberation chamber can conveniently be used to measure ergodic multiple-input multiple-output (MIMO) capacity for over-the-air (OTA) tests.

The Effect of Zigzag Boundaries on the Reverberation Chamber Performance
IEEE Access, 2021 The stirrer design is important in a reverberation chamber measurement system. Previous study shows that the rotating radius of the stirrer plays a key role for the stirrer performance. However, to identify the contribution from the structure, optimizing

An improved model for antennas in reverberation chambers [PDF]
2010 IEEE International Symposium on Electromagnetic Compatibility, 2010 We present an improved model for antennas in a reverberation chamber. The derivation of this model is more rigorous than previous derivations and models, but is still, admittedly, overly simplistic. However, this model should be applicable for a special class of antennas (those that can be modeled as an unknown 2-port network between the test port and ...
