An improved second order artificial material single layer (AMSL) method is proposed to predict the electromagnetic field in presence of conductive thin layers by the finite element method (FEM). The AMSL method is based on the replacement of the material physical constants of a conductive shield region with those of an artificial material. The new AMSL physical constants are analytically extracted by equating the equivalent transmission line (TL) equations governing the field propagation inside the shield with the FEM solution.

This paper deals with the assessment of the induced voltage in an unipolar pacing lead produced by the coil currents of a wireless power transfer (WPT) system for battery recharging of an electric vehicle (EV). In the first part of the work, the magnetic field distributions inside and outside an EV equipped with the WPT technology is carried out by finite element (FE) simulations using the artificial material single layer (AMSL) method.

In this work we provide an enhanced rule in order to model a buried object with a 2-dimensional symmetry by a wire-grid modeling for the Ground Penetrating Radar (GPR) archaeological applications. The buried object with a circular traversal section, is presented. The dependence of the rule as a function of the time and the frequencies, is presented. The validation was obtained using a numerical software based on the Finite Element Method (FEM) both in time and
