A comparison of MIMO antenna efficiency measurements performed in Anechoic Chamber and Reverberation Chamber [PDF]
, 2018 Multiple-input-multiple-output (MIMO) antenna will play a key role in the development of fifth generation (5G) wireless mobile communication systems due to their performance-enhancement capability in multipath environment. Antenna radiation efficiency is an important parameter for MIMO antenna system.

Test of 5G System in the Reverberation Chamber at mm-wave [PDF]
arXiv, 2023 The performance of a real fifth generation base station was studied by using a reverberation chamber as a real life propagating environment. Preliminary tests were conducted in order to define 5G base station operation conditions at mm-wave and emulated scenarios where reconfigurable intelligent surface(s) (RISs) will successively be tested ...

Use of Correlation Matrix to Assess the Stirring Performance of a Reverberation Chamber: a Comparative Study [PDF]
arXiv, 2014 The use of correlation matrices to evaluate the number of uncorrelated stirrer positions of reverberation chamber has widespread applications in electromagnetic compatibility. We present a comparative study of recent techniques based on multivariate correlation functions aimed at relating space-frequency inhomogeneities/anisotropies to the reduction of

Probability Distribution of the Quality Factor of a Mode-Stirred Reverberation Chamber
, 2012 We derive a probability distribution, confidence intervals and statistics of the quality (Q) factor of an arbitrarily shaped mode-stirred reverberation chamber, based on ensemble distributions of the idealized random cavity field with assumed perfect ...

Advanced Science, Volume 12, Issue 11, March 20, 2025.A novel strategy for integrating radiation and scattering is proposed. The simultaneous and independent modulation of amplitude and phase is achieved by employing space‐time coding of joint amplitude and phase of radiation scattering. Hence, beam scanning with ultra‐low sidelobe and in‐band ultra‐low scattering characteristics are realized. Furthermore,

Spatial resolution of late reverberation in virtual acoustic environments [PDF]
arXiv, 2021 Late reverberation involves the superposition of many sound reflections resulting in a diffuse sound field. Since the spatially resolved perception of individual diffuse reflections is impossible, simplifications can potentially be made for modelling late reverberation in room acoustics simulations with reduced spatial resolution.
