Post-processing of electric field measurements to calibrate a near-field dipole probe

Modelling radiated emissions of electronic components requires accurate measurements. The models based on electric and/or magnetic dipoles are essential to study electromagnetic interference problems in advanced simulation tools. Obtaining exact measurement data requires high-quality probes (i.e. probes that have both good spatial resolution and suitable sensitivity) belonging to the near-field test bench system. However, designing such probes is not possible. In this work, the authors have proven that an electric dipole probe can be calibrated by using the plane wave spectrum theory if the measured signal is noiseless. This is realised by using three kinds of `measurement signal`: analytical `measurement signal`, which is considered as an ideal signal; simulated `measurement signal` in three-dimensional simulation tool, based on the finite integration technique method, which presents only the probe intrusion effect; and finally the measured signal with the near-field test bench.
