A novel automated framework is presented for posture-aware evaluation of whole-body-averaged specific absorption rate (WB-SAR) to support epidemiological studies of exposure to electromagnetic fields (EMFs), with emphasis on children and adolescents in realistic living environments. A high-resolution Japanese voxel human model in combination with the finite-difference time-domain (FDTD) method is used to quantify posture-dependent variations in WB-SAR across multiple incident directions and polarizations. The workflow substantially reduces the time and effort required to generate and simulate diverse posture scenarios at scale. By capturing posture-induced changes in SAR distribution, the framework improves the fidelity of dosimetry inputs for large-scale epidemiological analyses. |
