A Rigorous Method to extrapolate Radiated Susceptibility from Near-Field Scan Immunity

International audienceNear-field injection or near-field scan immunity is a promising method for the analysis of the susceptibility of electronic boards and circuits. The resulting immunity map provides a precise localization of the sensitive area to electromagnetic disturbances to a given near-field source. However, the extrapolation of the immunity to another radiating source, either in near or far-field, is not trivial. This paper aims at proposing a rigorous post-processing method of near-field scan immunity results to extrapolate radiated immunity in other disturbance conditions, e.g. far-field illumination. The method is described and validated through simulation case studies
