Analysis of Different Scalar Probe Compensation Methods for an Array of Near-Field EMI Probes

This article proposes and analyzes two possible methods to compensate the raw near-field data obtained with an array of probes. The first method is based on spatial compensation procedure for a single probe modified toward second use standard spectral (plane wave) single-probe compensation. To latter, guidelines how design modify overall measurement such that mutual coupling edge effects have less influence are given. different tested in simulation compared performance probe. It shown compensation, combination proper design, will result error as low same technique used also improves results comparison regular calibration. However, not enough be postprocessing due ill-conditioning. shows path much needed, fast, accurate measurements.
