Emulation of MIMO nonisotropic fading environments with reverberation chambers [PDF]

open access: yes, 2008
Some recent publications have extended the emulating capabilities of reverberation chambers. While polarization imbalance has been removed and Ricean-fading environments are now properly emulated, these chambers are still limited to isotropic nonline

Employing Frequency-Modulated Signals for Tonal Excitation in Airborne Sound Insulation Measurements

open access: yesEngineering Transactions
To enhance the similarity of acoustic insulation testing conditions in the laboratory, a tonal signal was employed as the excitation signal, reflecting real-world scenarios, such as transformer noise.

Reverberation Chambers for Over-the-Air Tests: An Overview of Two Decades of Research

open access: yesIEEE Access, 2018
The reverberation chamber (RC) has traditionally been used for electromagnetic compatibility tests. About two decade ago, it found application in various over-the-air (OTA) tests of antennas and wireless devices.

Approximation and analysis of transient responses of a reverberation chamber by pulsed excitation [PDF]

open access: yesAdvances in Radio Science, 2020
Reverberation chambers show transient behaviour when excited with a pulsed signal. The field intensities can in this case be significantly higher than in steady state, which implies that a transient field can exceed predefined limits and render test ...
