Smart Glasses Radiation Effects on a Human Head Model at Wi-Fi and 5G Cellular Frequencies

Specific absorption rate and temperature rise distributions in a human head due to electromagnetic energy produced by an adjacent antenna integrated into a smart glasses are evaluated. These distributions are calculated with the use of a dispersive algorithm at 2.4 and 4.9 GHz in a single simulation. This algorithm is based on integrating the Debye model of human head tissues parameters into the finite-difference time-domain method by using the auxiliary differential equation approach and then calculating the SAR and temperature rise distributions in the head with the use of bioheat equation.
