Base-case model for measurement uncertainty in a reverberation chamber including frequency stirring (2017)
Journal Article
Gifuni, A., Bastianelli, L., Moglie, F., Mariani Primiani, V., & Gradoni, G. (in press). Base-case model for measurement uncertainty in a reverberation chamber including frequency stirring. IEEE Transactions on Electromagnetic Compatibility, https://doi.org/10.1109/TEMC.2017.2763627

We address the uncertainty of reverberation chamber (RC) measurements in presence of both mechanical and frequency stirring (FS). A base-case model is derived for reverberation fields affected by the measurement uncertainty due to the lack of a perfe...
