*2.1. Car Modeling*

The compact vehicle considered in this paper is the FIAT 500, as described in [15] and freely accessible at this link https://github.com/cadema-PoliTO/vehicle4em (accessed on 26 October 2021). Once again, onlythe chassis of the car was considered and modeled as a surface mesh in order to exploit the capabilities of the numerical formulation, which is based on the hybrid BEM/SIBC method [18].

In contrast to [15], where the material properties of aluminum and carbon fiber were selected for the car body, in this study, a conductivity of *<sup>σ</sup>* <sup>=</sup> <sup>2</sup> <sup>×</sup> <sup>10</sup><sup>6</sup> S/m and a relative magnetic permeability of *µ<sup>r</sup>* = 300 have been adopted. These values correspond to common steel with moderate shielding capabilities, as suggested in [19].
