Design of Chaotic Reverberation Chambers
2019 URSI International Symposium on Electromagnetic Theory (EMTS), 2019Deforming the geometry of a rectangular reverberation chamber (RC) improves the field disorder and the chaoticity of the RC field, even in presence of traditional stirring mechanisms. We study how position and number of hemispherical wall diffractors affect the transmission-based modal overlapping of a real life RC facility.

Load Optimization in Reverberation Chambers
2021 15th European Conference on Antennas and Propagation (EuCAP), 2021Optimal loading conditions of a reverberation chamber were investigated. The relevant figure of merit is discussed and defined. Multiple loading configurations were tested and results are reported. A simple model of how loading affects measurement uncertainty was developed and used to find a loading configuration that vastly improve results with ...

Boundary Fields in Reverberation Chambers
IEEE Transactions on Electromagnetic Compatibility, 2005A previous plane-wave integral representation for fields in a reverberation chamber is extended to analyze fields near the boundaries of a rectangular chamber. The field point can be located near a single wall, a right-angle bend, or a right-angle corner. Multiple image theory is used to ensure exact boundary conditions.

Reciprocity in reverberation chamber measurements
IEEE Transactions on Electromagnetic Compatibility, 2003Even though reverberation chambers have been used primarily for radiated immunity testing, they are reciprocal devices that are equally applicable for radiated emissions testing. This short paper presents the theory for radiated emissions testing and uses electromagnetic reciprocity theory to demonstrate the link between radiated emissions and immunity

Reverberation chambers at low frequencies
1999 IEEE International Symposium on Electromagnetic Compatability. Symposium Record (Cat. No.99CH36261), 2003This report documents the effects of corrugated walls on the uniformity of the electromagnetic environment within a small (1.8 m/spl times/1.2 m/spl times/0.8 m) reverberation chamber. The frequency band evaluated was 150 MHz to 650 MHz, taking 5 MHz steps. At each frequency 100 tuner steps were made, resulting in one complete tuner rotation.

Characterization of a Reverberation Chamber
2015Abstract : There is an increasing interest in the use of reverberation chambers with mode mixing for testing of electromagnetic susceptibility and immunity of a device under test because of its repeatability and measurement speed. A reverberation chamber is characterized as an environment with uniform, randomly polarized, isotropic fields throughout ...

Measurements in the Reverberation Chamber
The Journal of the Acoustical Society of America, 1939Our idea of the sound absorption coefficient of a surface is carried over from the optical analogy of the reflectivity of a surface for light. All reverberation theory and methods of measurement of absorption coefficients now extant are based on this conception of the dissipation of sound energy within a closed space.
