An iterative source reconstruction based method for radiated emissions prediction from PCBs

In this paper, an equivalent magnetic dipole array assumed to reproduce the radiated emissions from PCBs, iterative source reconstruction method is employed to reconstruct the equivalent sources based on phaseless magnetic near field planar scanning with the initial phase provided by a novel repeated particle swarm optimization (RPSO) process. Once the equivalent sources are determined, radiated emissions from PCB can be obtained. Finally, numerical results are presented to illustrate the effectiveness of this approach.
