Linking a One-Dimensional Reverberation Chamber Model with Real Reverberation Chambers [PDF]
2008 International Symposium on Electromagnetic Compatibility - EMC Europe, 2008 Our work focuses on the study of a simple yet complete one-dimensional reverberation chamber model presented previously. The statistical properties of the fields are introduced either by varying the width or the relative dielectric constant of a perturbing lossless layer. Our aim is to show the excellent agreement between this simple model and real RCs.

Metasurfaced Reverberation Chamber [PDF]
Scientific Reports, 2018 AbstractThe concept of metasurfaced reverberation chamber (RC) is introduced in this paper. It is shown that by coating the chamber wall with a rotating 1-bit random coding metasurface, it is possible to enlarge the test zone of the RC while maintaining the field uniformity as good as that in a traditional RC with mechanical stirrers.
