Energy Absorption Mechanism of Head in the Near Field of Dipole

IEC, ETSI and other international standard organizations have drawn general standards for specific absorption rate (SAR) of EM radiation from various handle wireless communication equipment in the near field, and keeps on consummating related product standards. Comparing with the expensive and long time testing, the simulation technique has outstanding advantages, and it is applicable in terminal design, R&D and pre-authentication. In this paper, we take the dipole as a simple model to simulate the energy absorption mechanism of head in the near field by FDTD method, then compare and analyze with the experimental results, at last give some suggestion to improve the precision of simulation.
