Abstract

This article investigates the effect of gaze angle on the specific absorption rate (SAR) and temperature rise in human eye underelectromagnetic exposures from 0.9 to 10 GHz. Eye models in different gaze angles are developed based on biometric data. Thespatial-average SARs in eyes are investigated using the finite-difference time-domain method, and the corresponding maximumtemperature rises in lens are calculated by the finite-difference method. It is found that the changes in the gaze angle produce amaximum variation of 35, 12 and 20 % in the eye-averaged SAR, peak 10 g average SAR and temperature rise, respectively.Results also reveal that the eye-averaged SAR is more sensitive to the changes in the gaze angle than peak 10 g average SAR,especially at higher frequencies.
