Numerical Prediction of SAR and Thermal Elevation in a 0.25-mm 3-D Model of the Human Eye Exposed to Handheld Transmitters

A 3D numerical study is proposed to compute the specific absorption rate (SAR) and maximum temperature increase in the human eye exposed to RF fields generated by handheld transmitters. A very accurate model of the human eye is proposed using a very fine discretization with 0.25 mm cubic cells that permits to consider many eye tissues in the calculations. The numerical aspects of the bioheat equation solution in the human head are discussed. The temperature increase in the exposed human eye is predicted for widely used handheld transmitters, such as walkie-talkies, mobile phones and WiFi- based devices.
