Stochastic EMI sources localization based on time domain near-field data

The paper presents a planar stochastic EMI sources localization approach based on two-point time-domain data of electromagnetic near-field tangential components. The radiating structure is considered as a set of simple electrical dipoles arranged on a grid in the object plane. The autocorrelation and cross-correlation spectra of eradiated signals in two different space points are used to determine the distribution of dipole moments and to identify the parameters of the effective radiation sources. The modeling data was processed with the proposed localization procedure.
