Metasurfaced Reverberation Chamber [PDF]
Scientific Reports, 2018 The concept of metasurfaced reverberation chamber (RC) is introduced in this paper. It is shown that by coating the chamber wall with a rotating 1-bit random coding metasurface, it is possible to enlarge the test zone of the RC while maintaining the ...

Linking a one-dimensional reverberation chamber model with real Reverberation Chambers [PDF]
2008 International Symposium on Electromagnetic Compatibility - EMC Europe, 2008 Our work focuses on the study of a simple yet complete one-dimensional reverberation chamber model presented previously. The statistical properties of the fields are introduced either by varying the width or the relative dielectric constant of a perturbing lossless layer. Our aim is to show the excellent agreement between this simple model and real RCs.

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 ...

Impact of Temperature and Relative Humidity on Reverberation Time in a Reverberation Room
Buildings, 2022 Changes in acoustic parameters measured in a room may depend on the location and orientation of the sound source and microphones or on the reverberation conditions of the room.

Chasing the Wave in a Reverberation Chamber [PDF]
2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE), 2018 The power-delay profile is a critical characteristic of a reverberation chamber. In this paper the power-delay profile is used for the first time to study in high detail how a wave interacts with its environment in a reverberation chamber. This is done by tracking the wave, starting from its creation at the antenna reference plane with the antenna in ...

Optimization of Stirrer Designs in a Reverberation Chamber [PDF]
IEEE Transactions on Electromagnetic Compatibility, 2005 This paper describes an investigation into the key factors which contribute to an effective mode stirrer. The work concentrates on the lower frequency range, since all stirrers have poorer performance at low frequencies. The stirrer's shapes and sizes have been investigated, together with an optimization of the finer details in the stirrer's shape. The

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.
