摘要

近年来，人们对植入式心脏起搏器(PM)的电磁干扰进行了研究。然而，移动无线电终端在PM附近的比吸收率(SAR)的研究很少。本文对具有高分辨率源模型的无线无线电终端的SAR进行了计算。计算结果表明，由于PM壳体反射波的影响，2ghz时的SAR比900mhz时高4倍。然而，所有计算出的SARs都低于国际安全准则。

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

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.
