Biologic effects of electromagnetic radiation, dispersive head, FDTD method, multiphysics model, specific absorption rate, temperature riseAbstract
In this paper, the effects of radio frequency electromagnetic fields produced by base stations on a human head are investigated with the aid of a multiphysics model at multiple frequencies using a single simulation. This multiphysics model is based on integrating the Debye model of human head dispersive tissues parameters into the finite-difference time-domain method by using the auxiliary differential equation approach and then calculating the specific absorption rate and temperature rise distributions in the head with the use of bioheat equation. The effects of frequency and incident angle of radio frequency electromagnetic fields on the specific absorption rate and temperature rise distributions in the head are analyzed.
