This sensor consists of identical rectangular multi-coil, excited by two-phase sinusoidal current source in order to generate a rotating magnetic field and to avoid the mechanical rotation of the sensor. The fibers orientations, the longitudinal and transverse conductivities in each ply of carbon fiber composite material plate were directly determined with analysis of the impedance variation of each coil as function of its angular position. The inversion process is based on the use of artificial neural networks. The direct calculation associated with artificial neural networks makes use of 3D time-harmonic finite element method based on the&amp;nbsp;&lt;i&gt;A&lt;/i&gt;,&amp;nbsp;&lt;i&gt;V–A&lt;/i&gt;&amp;nbsp;formulation.</style></abstract><issue><style face="normal" font="default" size="100%">N°2</style></issue></record></records></xml>
