COMPUTATION OF SAR AND TEMPERATURE VALUES IN THE HUMAN HEAD
In this study, to examine the impact of distance, angle and frequency on the human head during the regular functioning of a mobile phone, a head model is constructed via COMSOL software dataset. The handset antenna has been configured with a patch antenna being a radiation source at 900 MHz, 1800 MHz and 2100MHz, respectively. Temperature increase and specific absorption rate distribution on the user’s head with various angles and distances are simulated by using finite element method. Moreover, the simulations are also repeated during the voice and video calls with varying distances. It is observed that the values that are obtained in the simulations are in good agreement with the basic limitations set up by IEEE and ICNIRP, designating that the safety restrictions will not be dared by the usage of user.
