Reverberation Chamber Measurement Correlation

IEEE Transactions on Electromagnetic Compatibility, 2012
This contribution evaluates the utility of several different metrics for studying correlation between reverberation chamber measurements collected at different stirrer positions. Metrics considered are the autocovariance, the correlation matrix, and two metrics based upon the entropy of the data correlation matrix: 1) the effective number of ...

Wave Impedance in Reverberation Chambers

IEEE Transactions on Electromagnetic Compatibility, 2014
This letter concerns probability density functions of the complex impedance of fields in mode-stirred reverberation chambers. They are based on the electric- and magnetic-field statistics derived for ideal reverberation conditions. The implications of these distributions on electromagnetic compatibility measurements using reverberation chambers are ...

Characterization of Reverberation Chamber

2021
This chapter gives the details about electromagnetic compatibility (EMC), which is an equipment characteristic or property – not to behave unacceptably in the electromagnetic interference (EMI) environment. The need to keep EMC in mind from the beginning of equipment development, given the ongoing distribution density of electronic equipment and its ...

Electronically reconfigurable reverberation chambers

The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014
The idea of an electronically reconfigurable reverberation chamber (ERRC) is introduced, whose purpose is to support over-the-air (OTA) testing in a compact and cost-effective way. In contrast to mechanically stirred chambers, the ERRC operates by randomly varying reconfigurable loads placed on the walls of the chamber.

Reverberant Chamber Enhancement

Journal of the IEST, 2015
Typical reverberant chambers used for High Intensity Acoustic Testing (HIAT) can achieve high sound pressure levels (SPL) across most of the applicable frequency range (20 Hz to 10 kHz), but they have limitations. Depending on the size of the chamber, low frequency chamber modes may be limited in the testing frequency range.

Introduction to reverberation chamber test method and a two-stirrer mini-reverberation chamber

2002 3rd International Symposium on Electromagnetic Compatibility, 2003
As a time-efficient and cost-effective EMC test facility candidate, the reverberation chamber has attracted much attention from academia and industries. The objective of the paper is to introduce its general background, standardisation status and practical applications, highlighting some of merit and non-merit associated with the reverberation chamber ...

FDTD-FVTD Comparisons in Reverberation Chamber

18th International Wroclaw Symposium and Exhibition on Electromagnetic Compatibility, 2006
Modelling of a Mode Stirred Reverberation Chamber (MSRC) using time-domain techniques is achieved by using Finite-Difference Time-Domain (FDTD) and Finite-Volume Time-Domain (FVTD) schemes. Advantages and difficulties related to time domain simulations in MSRC are underlined in this paper.

Reverberation chamber modeling using FDTD

1999 IEEE International Symposium on Electromagnetic Compatability. Symposium Record (Cat. No.99CH36261), 2003
This paper gives a definition of the uniformity of the reverberation chamber that is similar to the uniformity area as defined for the anechoic chamber, but is a volume instead of a plane. In this definition, the uniformity volume has 16 points in the space.

Reverberation Chamber: Eine preiswerte Alternative zur Absorberhalle? (Reverberation Chamber: A Low-Cost Alternative to Anechoic Chambers?)

teme, 2002
In diesem Artikel wird die Modenverwirbelungskammer (engl.: Mode-Stirred Chamber, MSC) bzw. Feldvariable Kammer (FVK) als alternative Testumgebung für Störfestigkeitstests mit ihren spezifischen Vor- und Nachteilen vorgestellt. Grenzen eines derzeit diskutierten Normentwurfs werden aufgezeigt und mit entsprechenden Messwerten untermauert.
