Semi-analytical modeling of eddy current inspection for anisotropic material presenting rough interfaces

Abstract: This paper deals with the computation of a quasi-static field induced by a 3D eddy current coil in homogeneous and anisotropic material presenting a local deformation in the planar geometry. Using a semi-analytical approach, we resolve Maxwell’s equations in the Fourier domain: the electromagnetic (EM) field is expanded as a sum of eigenmodes which are computed in the new curvilinear coordinate system presented by a new metric tensor. Analytically, the boundary conditions are applied to compute the unknown coefficients of the modal expansion. Numerical experiments are performed and simulation results are compared to FE data.

Keywords: Anisotropy (43), Curvilinear Coordinate Method, Modal expension, Scattering metrix,
