This paper discusses the integrated evaluation of the conductive and near-field noise suppression using magnetic circuit network. The proposed magnetic circuit evaluated the ferromagnetic resonance (FMR) loss and near-field intensity simultaneously and agreed with the measured value. The validity of the evaluation is successfully clarified. It is clarified that the near-field shielding effectiveness is maximized at the intrinsic FMR frequency, because the reluctance of the magnetic film is minimized. It is also clarified that the conductive noise suppression is maximized and the near-field shielding effectiveness is simultaneously minimized at the shifted FMR frequency by the demagnetizing field, because the magnetic circuit resonates. These results demonstrate that the proposed magnetic network model is of great usefulness for developing the integrated design method of the magnetic film-type noise suppressor.
