使用我们最近实现的并行有限差分时域计算系统在基于Linux的个人计算机上，我们研究了人体对便携式电话在人体头部的峰值比吸收率（SAR）的影响。考虑到整个人体，我们发现，与孤立的头部模型相比，1-和10-g平均空间峰值SAR的差异在5.3%以内，大脑和眼睛中SAR的差异在19%以内。此外，在大多数真实使用位置，我们发现，由于身体效应，SAR略有下降。这些结果进一步支持了在便携式电话的SAR评估中使用孤立的人头模型的基本原理。
Using our recently implemented parallel finite-difference time-domain computation system on Linux-based personal computers, we investigated the human-body effect on the peak specific absorption rate (SAR) in the human head for portable telephones. Taking into account the whole human body, we found that there was a difference within 5.3% for the 1- and 10-g averaged spatial peak SARs and a difference within 19% for the SAR in the brain and eyes compared to the isolated head model. Moreover, in most realistic-use positions, we found that the SAR was slightly decreased due to the body effect. These results further support the rationale of using an isolated human-head model in the SAR evaluation for portable telephones.
