The accuracy of equivalent dipole arrays for source modeling of electromagnetic fields is affected by several factors. In the step for extracting equivalent dipole arrays for a given source, there are three factors that can affect accuracy: scanning height, source spacing, and scanning gap. In the evaluation step of reconstructed fields, there are two other factors that can also affect accuracy: evaluation height and additional structures. In this paper, simple guidelines are suggested considering the three factors in extracting equivalent dipole arrays. Also, the effects of the evaluation height on accuracy of reconstructed fields are demonstrated in the presence of shielding or dielectric structures. A feature selective validation process was utilized to evaluate similarities between actual and estimated fields.
