Improvement of the Execution Performance for 3-D Impedance Method by Clarification of its Matrix Form Representation

Abstract

Recently, numerous research institution and companies conduct the investigation and the development of wireless power transfer (WPT) systems. Especially, WPT systems using intermediate frequency band, e.g. around 85kHz, magnetic field have gained attention for the charging method of electric vehicle. Therefore, there is growing concern about health effects induced by magnetic fields (MFs) of the intermediate frequency band. The 3-D impedance method (IM) is one of the techniques to evaluate the induced electric field and current density within the biological body caused by MFs exposure in the intermediate frequency band for which quasi-static approximation is applied.
