Abstract
The paper presents an equivalent circuit model of small magnetic laminated objects. The responses in the frequency domain of these laminates are significantly influenced by eddy currents which can exist even if the thickness of the magnetic films is smaller than the skin depth. These currents can circulate within the laminates because of the capacitive coupling across the dielectric layers separating the magnetic films. Using this model the effective permeability of the thin multilayer films has been computed also taking into account the displacement eddy currents. The results presented are in agreement with numerical and experimental tests available in literature. The authors have developed this model using the circuit theory because this approach has the major advantage of being simple to understand and easy to implement with a calculation code.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
