Abstract

This paper compares the numerical results for the induced electric field and the specific absorption rate (SAR) obtained using the hybrid FEM/BEM method in two detailed models of the human eye. The first model features the human eye placed in the free space, while the second one incorporates the eye model in the realistic head model obtained from the magnetic resonance imaging (MRI) scans. Although the preliminary analysis showed the similar distribution of the induced electric field along the pupillary axis obtained in both models, the numerical results for the SAR showed some discrepancy between the two models, which can be attributed to the high values of induced field in the corneal and scleral regions obtained in the compound eye model. The analysis could provide some helpful insights when carrying out the dosimetric analysis of the human eye exposed to electromagnetic radiation.
