An Effective EMI Source Reconstruction Method Based on Adaptive Dynamic Differential Evolution

In this paper, an effective electromagnetic interference source reconstruction method is proposed based on adaptive dynamic differential evolution. The performance of traditional dynamic differential evolution depends largely on the choice of the initial values. Compared with the traditional dynamic differential evolution method, the proposed method will update the hyperparameters adaptively. This hyperparameter adaptive mechanism will make the proposed method have stronger global search ability and more reliable convergence performance, thus reducing the impact of the initial values. By using the proposed method, the unknown source is replaced by equivalent dipoles based on the phaseless scanning magnetic fields. Simulation results demonstrate the effectiveness of the proposed method.
