Using FEM Simulation to Estimation of Active Implantable Medical Device EMI Characteristic in the 4G and 5G Sub-6 Frequency Bands

Abstract

This study aims to develop a method to evaluate the electromagnetic interference (EMI) characteristics of implantable medical devices (implantable cardiac pacemakers/implantable cardioverter-defibrillators) with respect to various radio wave-using devices using electromagnetic field simulation. In this paper, the relationship between EMI characteristics of implantable medical devices and RF frequencies under near-field and far-field exposure conditions was investigated through numerical simulations. As a numerical model, an implantable pacemaker embedded in a human phantom used in the EMI evaluation test is prepared, and the AIMD-EMI characteristics near the transmitter in the 4G and 5G Sub6 frequency bands are analyzed by electromagnetic field simulation based on the finite element method.
