“…It is seen that F Aij (a ij ) and F A (a) approach the cdfs for ideal isotropy more closely at the higher frequency and deeper inside the cavity, as expected, whereas large anisotropies occur when the wall is approached, on account of the EM boundary conditions for E. Although measurements and tests are typically chosen to be performed "far" from any wall so that d = 9 mm would not be a location for normal RC operation, some scenarios enforce such small distances, e.g., an electronic component near a shielding enclosure, where proximity effects would be observed. The consistency of the results for F Aij (a ij ) when approaching a wall has been shown in more detail in [13]. Fig.…”

A probabilistic characterization is performed for a class of field anisotropy coefficients for random electromagnetic fields. Ideal reverberation (isotropy), anisotropic stirring (polarization bias), and incomplete stirring or line-of-sight coupling (direct illumination) are investigated individually. For small degrees of planar anisotropy or bias, trapezoidal distributions are obtained, representing first-order departures from ideal rectangular distributions. Distributions for two definitions of total field anisotropies are found to be less sensitive than those for the individual planar anisotropies. The method and results are useful for calibration and validation of reverberation chambers when field anisotropy requires a separate assessment. Theoretical results are compared to measured data in two chambers.

“…Very often, for the sake of simplicity, planar and/or total anisotropy coefficients are defined as functions of averaged field values [24], i.e. : Threshold values for 'medium' and 'good' stirring, as a function of the number of samples, are reported in [2] and a rationale for these values is proposed in [24].…”
