Abstract
Using the finite difference time domain (FDTD) method, SAR distributions and temperature increase will be evaluated in a head model exposed to the field radiated from cellular phones and WLANs antennas. Bioheat equation with suitable boundary conditions will be solved to find temperature elevation and exposure time effect. Aging effect will be figured out also. The obtained results confirm the importance of performing a thermal analysis together with the dosimetric one. At the same levels of radiated power, SAR levels in the tissues are less than the safety limit recommendations, except in skin and CSF tissues. Moreover, it is found that the induced temperature elevation in the brain region, in all the examined conditions, never exceed 0.2℃. This value is well below the threshold for the induction of adverse
thermal effects to the neurons.
