We investigated the effects of noise suppression by interposing magnetic materials between the power and ground planes of a printed circuit board and focused on RF transmission through and radiation from the power bus. To reduce power bus resonance and radiation, we used a commercial noise suppression sheet, which is commonly used to suppress RF noise generated from electronic devices. We also examined a thin Ni-Zn ferrite film for practical use in the future. We found that power bus resonance and radiation could be mitigated owing to the imaginary part of complex permeability of magnetic materials. The thin ferrite film with a planar electromagnetic bandgap (EBG) structure helped suppress transmission and radiation in the EBG passband.
