Abstract

Two popular wireless communication devices are considered in this paper. Firstly, the Bluetooth which is one of the most popular mobile accessories and the Google glasses which are a representation of the new futuristic vision. It is well known that the absorption of electromagnetic waves on the human head for a certain period of time may lead to health problems such as headaches, or even worse, brain cancer. The Specific Absorption Rate (SAR) is simulated for three different head models and compared with the available international recommendations. The first model used is the Specific Anthropomorphic Mannequin (SAM phantom), as well as two realistic models of human head (i.e., a 34 years old adult and a 10 years old child). The simulations were performed using the finite difference time domain (FDTD) method and the frequency used to feed the antennas was 2.45 GHz.
