This paper deals with the numerical evaluation of the magnetic field produced by a wireless power transfer (WPT) system in an electrical vehicle (EV) made by carbon-fiber (CF) laminates that are modeled as homogeneous anisotropic layers. The numerically calculated magnetic field generated by a 7.7 kW WPT system operating at 85 kHz has been compared with the reference levels of the ICNIRP guidelines. The main conclusion is that the anisotropy of the composite laminate does not play a relevant role at the considered frequency. Furthermore, the shielding performances of the CF composite panels are very poor suggesting to introduce a thin metallic shield to mitigate the field.
