“…To improve NF sampling efficiency, researchers are dedicated to accelerating the scanning process [14][15][16][17][18][19][20][21][22][23][24][25][26][27]. [19] proposes an adaptive sampling strategy based on a region growing algorithm, which identified regions with drastic changes in the NF on the basis of roughly uniform sampling, and then densely and uniformly sampled these regions.…”

As one of the most useful methods in electromagnetic interference (EMI) diagnosis, near-field (NF) scanning is widely used in electromagnetic compatibility (EMC) evaluation of complex devices under test (DUTs). In this paper, a two-stage plane adaptive sampling algorithm is proposed to reduce the acquisition time in the process of NF scanning and to make reconstruction of the radiation source more efficient. The sampling method is based on the region self-growth algorithm and the Voronoi subdivision principle, significantly reducing the number of NF samples in the stage of solving the radiation source model through uniform and non-uniform two-stage sampling. Two experiments were conducted to verify the correctness and effectiveness by comparing with the traditional uniform sampling method.
