摘要： The present disclosure provides a method and system for creating dipole moment model. The method is applied to a tested circuit and includes: performing a near-field measurement on the tested circuit, to obtain a near-field electric field and a near-field magnetic field related to the tested circuit; performing a two-dimensional divergence calculation on the near-field electric field and the near-field magnetic field, to obtain a near-field electric divergence field and a near-field magnetic divergence field; performing a convolution calculation on the near-field electric divergence field and the near-field magnetic divergence field with a digital filter; and building a dipole moment matrix equivalent to the tested circuit according to a result of the convolution calculation.
