Abstract
This article investigates variations in specific absorption rate and temperature rise in human eye caused by changes in palpebral fissure, the extent of opening between eyelids, under GHz plane-wave electromagnetic (EM) exposures. Detailed human head models with different palpebral fissure features were developed with a refined spatial resolution of 0.25mm. These head models were then incorporated into both EM and bio-heat simulations, but using finite-difference time-domain method and finite-difference method, respectively. Maximum temperature rise in lens was found to be 0.8°C under EM exposure at 100W/m2. Results reveal that changes in palpebral fissure would produce a 0.23°C variation in maximum temperature rise in lens.
