Application of Dipole-Moment Model in EMI Estimation

This paper used magnetic near fields to extract the dipole-moment model to represent the real radiation source. This method prevents the measurement of electric fields so that the scanning time and points are saved significantly. These equivalent dipole-moment models can take the place of the real radiation source in the full-wave simulation tool. The electromagnetic interference between the real source and victim structures are well predicted in the simulation by the dipole-moment model. This is validated by a numerical example in this paper.
