A method to evaluate the characteristics of printed circuit boards containing magnetic films is proposed. By means of electromagnetic field distribution computed from a combined finite element method and strategic dual image method, the equivalent circuit parameters R, L, C are determined. The employed methodology which accounts for eddy currents, displacement currents and hysteresis is detailed in the case of 2D axisymmetric problems. Then two simple PCB configurations are investigated. The results clearly show that the NiZn ferrite composite material included in one PCB reduces EMI efficiently
