Coupling the electromagnetic inverse problem based on genetic algorithms with Moment´s method for EMC of circuits

In this paper, we present the inverse problem in electromagnetism based on the Genetic Algorithm method. We apply then, this method to structures having big dimension circuits and we show limits of this method in that case of structures. We propose after, a new technique which is based on the coupling of the inverse method in electromagnetism with the Moment´s method. The proposed hybrid method is implemented and is validated on simple structures by referring to simulation results made with the numerical software NEC. Results are compared to those obtained by the inverse electromagnetic method. Results analysis show that the proposed hybrid method is more appropriate to structures with big dimension circuits and with rectangular loops.
