Maximum Radiated Power Density From Electrically Large Sources—Comparing Probability Theory and Measurements

The unintentionally radiated power density from electrically large electronic equipment shows a strong directional dependence. The polarization of the emitted field is also a priori unknown. Time and economy makes it prohibitive to measure all orientations of the equipment. A simple probability model has been proposed to quantify the magnitude of the effect: the power received by a measurement antenna is exponentially distributed. We verify that simple model by measurements.
