Research on the substitute method of electromagnetic emulation for reverberation chamber

2009 5th Asia-Pacific Conference on Environmental Electromagnetics, 2009
Finite array of continuous wave superposition was adopted to simulate electromagnetic environment of reverberation chamber. Using this equivalent method it is not necessary to divide cavity mesh grid and calculate the reflect process of the chamber cavity time after time.

Radiation pattern measurements in reverberation chamber based on estimation of coherent and diffuse electromagnetic fields

2014 IEEE Conference on Antenna Measurements & Applications (CAMA), 2014
In a recent publication, authors showed that measurements of the maximum directivity of antennas were achievable in a reverberation chamber through extraction of the coherent part of the field. In this communication, we extend the method to the measurement of the radiation pattern within the main lobe of radiation.

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), 2019
Our 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.

Mixing Music Using Electromagnetic Reverberation Chamber [PDF]

2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE), 2018
Acoustic reverberation chamber (RC) is a good facility to create reverb effect in music mixing. This paper presents the use of an electromagnetic (EM) RC to generate acoustic reverb effects. Different to an acoustic RC, stirrers are often used in an EM RC.

Measurement of the SAR Value Distribution in an Electromagnetic Reverberation Chamber [PDF]

2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC), 2018
E2018BioERCfinal. 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

Reverberating chambers as sources of stochastic electromagnetic fields

IEEE Transactions on Electromagnetic Compatibility, 1996
Reverberating chambers are of recognized relevance in many EMC applications since they allow us to generate a reference electromagnetic statistical field. This paper investigates the electromagnetic field in reverberating chambers. Reverberating chambers are large overmoded cavities wherein a nonstationary electromagnetic field is present.

The Polarization Purity of the Electromagnetic Field in a Reverberating Chamber

IEEE Transactions on Electromagnetic Compatibility, 2016
The quintessence of electromagnetic fields propagating in complex environments is its stochastic nature. The canonical test facility to emulate such a complex case is the reverberating chamber (RC). In order to design, test, and model the electromagnetic field in an RC, one must consider the vectorial nature of the field.

Theoretical analysis of electromagnetic reverberation chamber

2005 IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, 2006
There are several disadvantages in the current electromagnetic theory of reverberation chamber analysis. The first disadvantage is that the current theory can only estimate number of electromagnetic modes and statistic uniform field distribution under high order modes circumstance inside a reverberation chamber, not give a systematic electromagnetic ...

Reverberating chamber electromagnetic field in presence of an unstirred component

IEEE Transactions on Electromagnetic Compatibility, 2000
A theoretical model for the electromagnetic field within a reverberating chamber in presence of an unstirred component is presented. Due to the stochastic nature of the electromagnetic field within the chamber, a statistical electromagnetic approach is developed and tested versus measurements.
