This paper deals with the electric and magnetic field (EMF) safety aspects of a wireless power transfer (WPT) system based on magnetic resonant coupling between two coils. The primary coil is assumed to be on-body, while the secondary coil is assumed to be inside the human body and connected to a battery recharge system of an active implantable medical(More)
This paper deals with wireless power transfer technology applied to charge the battery of a short-distance electric vehicle. Different compensation topologies (series&#x2013;series and <italic>LCC</italic> compensations) are examined and compared in terms of magnetic field emission and system efficiency. The investigation is carried out by simulations and(More)
A wireless power transfer (WPT) system based on magnetic resonant coupling is applied to a pacemaker for recharge its battery. The primary coil is assumed to be on-body, while the secondary coil is in-body. Three different configurations of the secondary coil are hereby investigated placing it inside the titanium case of the pacemaker, on the top surface of(More)
A circuit-based implementation of the Leontovich impedance boundary condition (IBC) is proposed. The surface impedance of a lossy medium is approximated by a series of first-order rational functions using the vector-fitting technique. Thus, an equivalent analogical circuit with lumped linear time-invariant parameters is derived, which is simply analyzed in(More)
This paper deals with the time-domain numerical calculation of electromagnetic (EM) fields in linearly dispersive media described by multipole Debye model. The frequency-dependent finite-difference time-domain (FD2TD) method is applied to solve Debye equations using convolution integrals or by direct integration. Original formulations of FD2TD methods are(More)
This paper deals with the magnetic shielding of the field generated by a wireless power transfer (WPT) system at the frequency of 20 kHz.

The performances of the WPT system and the magnetic field shielding effectiveness (SE) in presence and(More)
This study deals with the design of an inductive Wireless Power Transfer (WPT) system to recharge the battery of a pacemaker. A co-simulation tool is developed using both circuit and electromagnetic field models to simulate all parts of a WPT system for a pacemaker. The pacemaker equipped with the secondary coil of the WPT system is assumed to be implanted(More)
This paper deals with the magnetic shielding of the field generated by a wireless power transfer (WPT) system in air at the frequency of 20 kHz.

The paper provides an investigation of a possible application of wireless power transfer (WPT) technology to recharge the battery of a short-distance electric vehicle. The performance of the WPT system working at 85 kHz is first investigated by simulations. A robust LCC compensation network suitably tuned is then investigated with the goal to analyze the(More)
An efficient implementation of low order surface impedance boundary conditions (SIBCs) for the finite-difference time-domain (FDTD) method is presented. The surface impedance function of a lossy medium is approximated with a series of first-order rational functions by using the vector fitting (VF) technique. Thus, the resulting time-domain convolution(More)
