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.

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

Angle-Dependent Absorption of Sound on Porous Materials
Acoustics, 2020 Sound-absorbing materials are usually measured in a reverberation chamber (diffuse field condition) or in an impedance tube (normal sound incidence). In this paper, we show how angle-dependent absorption coefficients could be measured in a factory-type ...

Correlation and Capacity Calculations with Reference Antennas in an Isotropic Environment
International Journal of Antennas and Propagation, 2012 A reverberation chamber is a convenient tool for over-the-air testing of MIMO devices in isotropic environments. Isotropy is typically achieved in the chamber through the use of a mode stirrer and a turntable on which the device under test (DUT) rides ...
