Alternative Definitions of the Field Anisotropy in a Reverberation Chamber

In this paper, we propose alternative definitions on the statistical field anisotropy in a reverberation chamber. The proposed definitions are more direct and intuitive compared to the conventional definitions in the IEC 61000-4-21 standard. The equivalency between the proposed definitions and the conventional definitions is presented. The probability density and cumulative distribution functions of the proposed anisotropy coefficient are derived. Measurement demonstrations are also given.
