Numerical evaluation of Specific Absorption Rate with two realistic mobile phone models

Abstract

This thesis is a numerical evaluation of SAR compliance assessment with realistic exposure conditions using accurate human and mobile phone models. Four hand models with four adult and five child head models were simulated with two accurate Nokia mobile phone models, 6630 and 8310. In total over 400 simulations were run with comparable settings to achieve possibility to consider different aspects appearing in the results. No systematic differences between models are observed, however some differences between different anatomical models, which in some cases seem to be related to the distance of the source and tissues in the cheek area, are observed. Most of the differences seen in the results are also related to the hand holding the device. Our results do generally confirm the SAM phantom conservativeness in the tested configurations. Important observations about phone material assignment and the connection of head and hand voxels in the simulation domain were made during the process.
