DESCRIPTION:This presentation will focus on the development and simulation 
 procedure to determine the specific absorption rate (SAR) and the correspo
 nding temperature rise due to electromagnetic waves incident on a human he
 ad. The human head model is based on medical magnetic resonance images (MR
 I) that are discretized to fit in the simulation domain. The frequency dep
 endence of the human head tissues is considered in the simulation for mult
 i-frequency field exposure. The sources of the electromagnetic radiation a
 re: Antennas on a cellular base station tower\, a small multiband antenna 
 close to the side of the human head\, simulating a cellular phone\, and a 
 dual band antenna embedded in a smart eyeglasses. The dispersive material 
 formulation of the finite difference time domain (FDTD) method is used in 
 order to accurately represent the frequency dependence of the head tissues
 . A three terms Debye model of the head tissue is utilized in the FDTD sim
 ulation. The bioheat differential equation is used to determine the temper
 ature in the head tissues before and after exposure to the electromagnetic
  radiation. Results will show the SAR and temperature distribution in the 
 human head\, and also will emphasize the efficiency of the developed code 
 for multi-frequency analysis with a single simulation for dispersive type 
 material.\n\nCo-sponsored by: AP-S chapters in Australia\n\nSpeaker(s): Pr
