Research on High Precision Simulation Technology of Specific Absorption Rate of Human Head Model

The effect of electromagnetic radiation from mobile phones onto human head tissue is mainly investigated. Two types of millimeter wave antennas have been used as the radiation source for the specific absorption rate (SAR) test, and been the electromagnetic model of mobile phone on the human head model as well. The grid precision of the established model reaches below
$\lambda/10$
at the millimeter wave frequency of 28GHz. Furthermore, the modeling by using FDTD method and simulation process of high-precision human head model are also introduced, and the results are verified in line with the current international criteria.
