Far-Field Amplitude Estimation of General Electromagnetic Radiators from Close-Field Measurements

Abstract

The m o d e l l i n g of radiation from e l e c ­ tronic equipment is investigated. Several radiation mechanisms for conductive enclosures are identified, physically model led and empir­ ically characterized from far-field (10 m) measurements. This information is used to generate computer models that relate closefield to far-field radiation. Comparisons between measured far-field amplitude data and computer-modelled field estimations generated from measured c l o s e-field data are shown for various sources. Finally, measurement errors are discussed.
