Abstract :
Recently, electromagnetic interference (EMI) of an implanted pacemaker induced by a mobile radio terminal has been investigated. However, there are few studies of specific absorption rate (SAR) around the pacemaker induced by the mobile radio terminal. In particular, the SAR in such a case due to the electromagnetic wave of very high frequency (VHF) band has not been investigated. In this paper, SAR distributions around a pacemaker model embedded into the torso model by a wireless radio terminal in VHF band, which are used in police officers, airport employees etc., are calculated. As a result of calculations, possibilities of increasing the SAR were observed.
