Simulation and assessment of pacemaker RF exposure (2.4 GHz) by PIFA antenna

The proposed paper deals with simulation and analysis of the radiofrequency field (2.4 GHz) inside the human tissue using a multi-layered skin and pacemaker model. The research was carried out using electromagnetic modelling based on the Finite Integration method. The simulations were performed in terms of computing electric field distributions calculated for four different hypodermis layer thickness. The focus was on near-field exposure modelled by PIFA antenna, commonly used in handheld devices. The results have shown that higher hypodermis layer causes higher absorption of electromagnetic field which leads to lower values of electric field strength on the pacemaker casing.
