Abstract
In this paper, an approach is proposed to predict the maximum far-field radiated emission based on phaseless near-field scanning. The maximum radiated emission from printed circuit boards is assumed to be produced by dominant magnetic dipoles located by the near-field measurement. The particle swarm optimization technique is then employed to identify the complex moment components of the dipoles. Once the dominant dipoles at each emission frequency are determined, the maximum far-field radiated emission in the interested frequency range can be calculated using the method of moments. The proposed approach allows a quick assessment of far-field radiated emission precompliance in a wide frequency range by near-field scanning. Experimental results are presented to show its feasibility and effectiveness.
