Radiation of electromagnetic waves from various §sources including cellphone has become a raising §public concern. This has motivated us to study the §scattering and absorption of EM waves on a human §head based on the coupled hp finite/infinite element §(FE/IE) method.The electromagnetic power deposition §and transfer properties of a G1 continuous head §model reconstructed from magnetic resonance imaging §(MRI)data are investigated. The discretization error §is controlled by a self-adaptive process driven by §an explicit a posteriori error estimate. Based on §the benchmark problem of reproducing the Mie series §solution, the scattering of a plane wave on the §curvilinear head model is used to evaluate the hp §FE/IE approach and calibrate §the error bound. The radiation pattern from a short §dipole antenna modeling a cell phone, is analyzed in §terms of the level and distribution of the specific §absorption rates (SAR). The numerical experiments §show that the hybrid hp FE/IE implementation is a §competitive tool for accurate assessment of human §electromagnetic exposure.
