The relation between electromagnetic field distributions in a human head and near-field of near-by electromagnetic sources

摘要

The dose characteristics in a human head exposed to the near field of various fundamental sources have been evaluated numerically by the finite-difference time-domain (FDTD) method. It is shown that the electromagnetic fields in the human head strongly depend on the near-field characteristics of the sources. In the case of the infinitesimal short electric dipole, it is also suggested that the internal E- and H-field as well as current density and SAR are closely related with the incident H-field.
