Converting total-radiated-power measurements to equivalent E-Field Data

This paper discusses the procedure to convert total-radiated power measurements data to equivalent electrical field data, which might be get on a standardized test site. The algorithm in use is based on two parameters, which are the geometrical factor g_max and the directivity of equipment under test (EuT) D_max. Both parameters are unknown for unintentional radiators. The aim of this paper is to collect the published information to predict these parameters and to discuss the influencing factors to get a useful approximation for g_max and D_max. Especially the prediction of D_max depends on the effective size of the EuT described by the radius of a sphere containing the EuT.
