IEEE Transactions on Antennas and Propagation, 2022 This communication presents the antenna gain pattern estimation from backscattering coefficient measurement performed within a reverberation chamber (RC). The antenna backscattering coefficient is measured for two load conditions, namely, an open circuit

Frequency characterization of reverberation chambers [PDF]
Proceedings of Symposium on Electromagnetic Compatibility, 2002 A series of measurements to investigate the modal structure of a reverberation chamber were conducted at the Dahlgren Division of the Naval Surface Warfare Center, Dahlgren, Virginia. These measurements were Phase I of a project to determine the frequency dependent characteristics of the fields in a reverberation chamber.

IEEE Transactions on Antennas and Propagation, 2021 This article deals with the ability to perform radar cross section (RCS) pattern measurements within reverberation chambers (RCs). The characterization principle is based on the estimation of the backscattered field from the target at a far-field ...

The Effect of Noise on Reverberation-Chamber Measurements of Antenna Efficiency
IEEE Transactions on Antennas and Propagation, 2021 In this work, we show that high antenna frequency selectivity can make it more challenging to accurately measure antenna efficiency in a reverberation chamber (RC) when using the two-antenna method since electronic noise can affect the measured stirred ...

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.

Diffuse field cross-correlation in a programmable-metasurface-stirred reverberation chamber
Applied Physics Letters, 2021 Programmable metasurfaces can endow complex scattering environments with reconfigurability. Here, we make use of these configurational degrees of freedom to retrieve the impulse response between two passive antennas via cross-correlation techniques.

Chamber-Decay Time in a mm-Wave Reverberation Chamber
2021 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (APS/URSI), 2021 In this work, we present results of a novel mm-wave reverberation chamber, where we discuss the role of the chamber quality factor and chamber decay time, or time constant, for mm-wave applications.
