This paper deals with the application of the recently developed artificial material single layer method to efficiently model a thin conductive anisotropic material using commercial software tools based on the finite element method. In the present work the method is applied to the prediction of the magnetic field in an electric vehicle made with metal or carbon fiber reinforced polymer (CFRP) bodyshell and equipped with a stationary wireless power transfer system. Simple tests are presented to show the performance of the method.

This paper deals with the extension of the artificial material single-layer (AMSL) method, recently developed to model electromagnetically a thin conductive material using the finite-element method (FEM), to the more general case of transversally anisotropic shields. The analogy between the field equations and the multiconductor transmission line (MTL) equations is here used to calculate the admittance matrix of a thin anisotropic material. This admittance matrix is then imposed to be that of an equivalent circuit with lumped parameters.
