The numerical evaluations on SAR around an implanted cardiac pacemaker by a mobile phone of multiple operating frequencies

Abstract

In recent years, electromagnetic interference (EMI) of an implanted cardiac pacemaker (PM) has been investigated. However, there are few studies of specific absorption rate (SAR) around the PM by the mobile radio terminal. In this paper, SAR due to a wireless radio terminal which has high resolution source model is calculated. As a result of calculations, SAR at 2 GHz was 4 times higher than that at 900 MHz because of reflection wave at PM housing. However, all calculated SARs were below the international safety guidelines.
