Electromagnetic Waves Interaction with a Human Head Model for Frequencies up to 100 GHz
Keywords:
Dispersive tissues, FDTD method, human safety standard, penetration depth, millimeterwave radiation, SAR, temperature riseAbstract
Specific absorption rate (SAR), penetration depth, and temperature rise in a one-dimensional (1D) dispersive human head model due to electromagnetic fields radiated by wireless communication systems operated up to 100 GHz are evaluated with the use of a Multiphysics model. In this model, the Debye model of human head tissue parameters is integrated into the finite-difference time-domain method with the use of the auxiliary differential equation to obtain solutions at multiple frequencies of interest using a single simulation. Then, the SAR, peneration depth, and temperature rise in the 1D head model are calculated for each frequency of interest. The effects of frequency on the SAR, penetration depth, and temperature rise in the head are investigated.
