The most comely used standards or guidelines throughout the world are FCC OET65 Supplement C, IEEE/ANSI C95.1, IEEE Std-1528, CENELEC prEN50360, prEN50361 and ES59005. Also, we have SAR limits (1.6W/Kg for localized exposure) in our country. For realize the deposition of electromagnetic energy emitted by handset in human head, this study use simplified phantom of different shapes and sizes. Observe the SAR distribution and power absorption by changing the inner structure, electrical properties of tissue, sizes and shapes of the phantom, and the relative distance between phantom and handset to investigate the absorption mechanism at 900MHz when RF-sources operating in the very close proximity of the head.
