Abstract :
There are many commercial shields for 3G and 4G mobile phones re-emerging onto the market, claiming specific absorption rate (SAR) reduction; however their effectiveness is questionable. In this paper, their SAR and induced electric field (E-field) are measured, and the corresponding induced E-field inside the human body with and without implanted medical devices is analyzed. Results have indicated that the SAR values, either with and without the shields have shown no particular impact, and the induced E-field on a human body with and without any implanted pacemaker are similar.
