Validation of Vibrating Intrinsic Reverberation Chamber using Computational Electromagnetics
2019 Joint International Symposium on Electromagnetic Compatibility, Sapporo and Asia-Pacific International Symposium on Electromagnetic Compatibility (EMC Sapporo/APEMC), 2019Our study demonstrates a validation of the computational electromagnetics modeling and a simulation of a vibrating intrinsic reverberation chamber (VIRC). The VIRC generates a random electromagnetic environment by shaking the flexible conductive walls to vary the boundary conditions.

Investigating electromagnetic exposure of communication cables in reverberant chambers
IEEE International Symposium on Electromagnetic Compatibility, 2003As distributed electronic systems become more complex, the electromagnetic compatibility (EMC) behaviour of the communication cables becomes more significant. Hence a range of test methods must be developed that will provide an adequate measure of the cable's interference susceptibility. One such method is the 'mode stirred reverberation chamber method'

Measurement of the SAR Value Distribution in an Electromagnetic Reverberation Chamber
2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC), 2018E2018BioERCfinal. It is quantified by the specific absorption rate (SAR). Differing thermal and non-thermal effects requires suitable tissue samples under well-defined environmental parameters (e.g. temperature and humidity) and an exposure setup providing defined deterministic or probabilistic EM fields. Multiple test setups exist, e.g. open area test

Acoustic and electromagnetic reverberation chambers: Similarities and differences
2016 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC), 2016Acoustic reverberation chambers predate electromagnetic (EM) reverberation chambers. EM reverberation chamber researchers occasionally make reference to acoustic equivalents when describing test methods and results. However, most EM reverberation chamber users are not familiar with acoustics and may not be aware of similarities and differences.

The Journal of the Acoustical Society of America, 1961
The upper limits for the reverberation time and Q factor of acoustic reverberation chambers with perfectly rigid walls with a smooth surface are determined. The reflection factor for a rigid wall of arbitrary thermal conductivity is determined from a consideration of the viscosity and heat conductivity-boundary layer.

Carbon foam electromagnetic mm-wave absorption in reverberation chamber
Carbon, 2019Abstract The electromagnetic (EM) absorbing cross section (ACS) of carbon foams in the mm-wave frequency range 50–70 GHz is analyzed by means of a reverberation chamber (RC) set-up. Carbon foams are lightweight cellular materials which are believed to provide benefits in EM interference/compatibility (EMI/EMC) issues, due to their significant thermo ...

Coupling of Stochastic Electromagnetic Fields to a Transmission Line in a Reverberation Chamber
IEEE Transactions on Electromagnetic Compatibility, 2011A new method for the numerical simulation of the stochastic electromagnetic environment of a mode-stirred chamber is presented in this paper. This method is based on the plane-wave integral representation for the fields and uses a Monte Carlo simulation to replace the analytical integration by numerical summation.

Full Wave Computation of the Electromagnetic Field in Chaotic Reverberation Chambers
2019 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2019The geometry deformation of a rectangular shaped reverberation chamber (RC) improves the field mixing and the chaoticity within the RC, in addition to traditional stirring techniques. We noted how the position and number of hemispherical diffractors affect the RC, evaluating their typical key performance parameter such as the number of uncorrelated ...
