SAR Evaluation with Daily Posture Variability: Toward Epidemiologically Relevant Assessment Using an Automated Numerical Simulation Framework
Abstract
With the increasing use of wireless devices, quantitative assessment of human EMF exposure in daily life has become important. However, most dosimetry studies rely on simplified single-source exposure and upright postures. To develop novel EMF dosimetry for epidemiological research, this study proposes an automated FDTD framework to evaluate WB-SAR and Max 10-g psSAR under stochastic multi-source environments. The results show that the mean WB-SAR remains relatively stable, whereas localized SAR values increase as exposure conditions become more complex. These findings indicate the importance of considering posture and stochastic exposure configurations for realistic SAR-based dosimetry.
