人体暴露于射频电磁场的不良健康影响已成为越来越多的关注。根据SAR评价安全性。由真实的人的物理特征的差异引起的SAR中的变化是几个重要问题之一。在这项研究中，我们开发了计算人体模型与不同的身体类型，我们提出的体积变形技术，以产生的模型从磁共振成像数据的目标人使用现有的人体模型。我们还证明了SAR特性的人体模型与不同的身体类型暴露在垂直和水平极化的电磁波范围从30 MHz到6 GHz的多GPU加速三维FDTD求解器。
The adverse health effects of human exposure to RF-EMFs have become of increasing concern. The safety is evaluated on the basis of the SAR. Variability in the SAR caused by differences in the physical features of real people is one of the several important issues. In this study, we developed the computational human models with different body-types by our proposed volume deformation technique to generate the model from magnetic resonance imaging data of target persons using existing human models. We also demonstrated SAR characteristics in human models with different body-types exposed to vertically and horizontally polarized EM waves ranging from 30 MHz to 6 GHz using the multi-GPU accelerated three-dimensional FDTD solver.
