An analysis of the specific absorption rate (SAR) in a model of a human head, composed of several tissues, as a result of the exposure to two electromagnetic sources working on the 2.4 GHz WiFi band is presented; the devices are a WiFi modem and a cell phone. The electric field necessary to get the SAR is calculated using a simulation based on the finite-difference time-domain (FDTD) method. With a view to evaluating how the electromagnetic field interacts in different tissues, specially in brain tissues, the SAR is broken down by tissue, and the data are displayed using box-plots. Nine other tissues were used in the head model. Finally, using a simple bio-heat equation, a simple analysis of the temperature increase is done as well.
