Reducing RF (radio frequency) magnetic field radiation from electronic devices is one of important techniques for the EMI (electromagnetic interference). Far field measurement is widely used to measuring RF magnetic field radiation from a device. But, it is difficult to identify detailed positions of far field sources from the far field measurement. On the other hand, near field measurement can be used to measuring just above a device. Magnetic fields measured at near fields contain both of components of far and near field sources. In this paper, an approach for visualization of far magnetic field sources has been proposed. The proposed approach is applied to a simple simulation to identifying both of far and near magnetic fields from a measured magnetic field distribution. As a result, simulated results have been showed that far fields and its sources can be visualized from a measured magnetic field distribution at close range.
