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 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 ...

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 ...

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

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.

Buildings, 2021 Insufficient diffuseness is the major cause of the poor repeatability and reproducibility of building acoustical measurements in a reverberation chamber. Inaccurate results were reported for the prevailing methods in ISO and ASTM standards. Many previous

Experimental investigation of the Metasurfaced Reverberation Chamber
Electronics, 2023 To verify the concept of the metasurfaced reverberation chamber (MRC) which was proposed. This paper reports on measurements in the reverberation chamber (RC) performance by using a 1-bit random coding metasurfaced stirrer. The measurement results are validated and compared with that from two mechanical stirrers (horizontal stirrer and vertical stirrer)

A Fast Finite-Difference Time Domain Simulation Method for the Source-Stirring Reverberation Chamber
International Journal of Antennas and Propagation, 2017 Numerical analysis methods are often employed to improve the efficiency of the design and application of the source-stirring reverberation chamber. However, the state of equilibrium of the field inside the chamber is hard to reach.

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 ...
