Electromagnetic Reverberation Chambers

2011
Dedicated to a complete presentation on all aspects of reverberation chambers, this book provides the physical principles behind these test systems in a very progressive manner. The detailed panorama of parameters governing the operation of electromagnetic reverberation chambers details various applications such as radiated immunity, emissivity and ...

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.

Rationale for reverberation chamber testing

2013 US National Committee of URSI National Radio Science Meeting (USNC-URSI NRSM), 2013
Summary form only given. Several test facility options for conducting electromagnetic compatibility testing including immunity, emissions, and shielding effectiveness are available. Generally each facility provides a different test electromagnetic environment. A reverberation chamber is a cavity enclosed by conducting surfaces with a method of exciting

Qualification of WEAL Reverberation Chamber

The Journal of the Acoustical Society of America, 2001
Western Electro-Acoustic Laboratory (WEAL) has recently qualified a new reverberation chamber. Qualification measurements were performed for absorption testing (ASTM C423) and sound power testing (ANSI S12.31 and S12.32). Results are shown at various stages of the qualification.
