Numerical Analysis of Multifetal Exposure to Radiofrequency Electromagnetic Fields

To numerically assess the multifetal exposure to radiofrequency fields (20 to 3600 MHz), one twin-fetal model was reconstructed and was merged to an adult female model to form the fetus-pregnant model. Numerical simulations using plane-wave revealed that the female adult was always significantly exposed compared to the fetuses for the surveyed frequency band. At lower frequencies, the twin fetuses were homogeneously exposed but the whole-body dosimetric difference could be as high as 270% at higher frequencies.
