Abstract

In this paper, several modeling approaches are taken to investigate the effects of 5G millimeterwave (MMW) radiation on the human eye. As the effects of MMW radiation from 26-34 GHz on the eye have not yet been examined directly, understanding them allows for the prediction of biological damage caused by commercial devices operating in the aforementioned frequency range. Models of varying complexity are used to examine the degree to which physical fidelity and specific tissue properties (e.g., losses in different types of tissue) affect the expected overall power deposition, through the specific absorption rate (SAR). Specifically, a simplified physical geometry was used to approximate the system, namely layered dielectric slabs, before comparing it to a meshed model of an eye. The simplified model allows for the general effects of parallel and perpendicular polarization to be examined, in addition to estimating the regions in which the highest SAR will occur. Physical tests were performed to validate the ability of this model to predict the power deposition and resultant heating in layered lossy media.
