An Effective Method of Probe-calibration in Phase Resolved Near-field Scanning for EMI Application
Electromagnetic models of ICs and modules are helpful for approximately predicting the emissions of a system or the intra-system coupling. One of the modelling methods is to calculate equivalent magnetic or/and electric current sources from near-field data above or around the under test (DUT). In this approach near-field scanning technique is used to capture sufficient field information. The scanned near-field data along the Huygens surface the emission source can be applied to source reconstruction far-field calculation.
