Whole-Body SAR simulations on a prolate spheroid using different plane wave polarizations up to 100 GHz

Abstract

A study on specific absorption rate (SAR) measurements using computational tools is presented. Using various numerical tools, ranging from full-wave simulators to physical optics, a prolate spheroid is irradiated by different polarized plane waves in the frequency range of 10 MHz - 100 GHz. For the low frequency range full-wave simulators were used to obtain the whole-body SAR of the prolate spheroid. When technical limitations were reached by this methodology, a physical optics approach was used to reach whole-body SAR measurements to a 100 GHz. As a side study, the electrical properties of water were studied with the goal of using them in both approaches. This project is a joint effort between the Technical University of Hamburg (TUHH) and the Technical Institute of Technology of Costa Rica (TEC).
