Modeling of Diffusion Layer Thickness Variation of Laminate in Case of a Current Supply

This paper discuses the modeling of the diffusion layer thickness variation impact on induced voltage. The numerical modeling of laminate with the diffusion layer is realized using finite elements code developed under Matlab environment. The solving of the 2D electromagnetic equation, in (r,z) plane, is performed by considering magnetic permeability variation of the diffusion layer. A comparison between the simulation results and experimental data shows a good agreement and permits the validation of the developed program as a step of a global study of homogenization process of a multi-scale structure.
