Heterogeneous versus homogeneous human models for dosimetry analysis using TLM simulation

The constant and rapid increase in connected devices popularity raises questions about their possible impact on living beings. Dosimetry is used to assess the levels of EM-exposure induced by these devices. Numerical methods become handy when measurements are impossible to conduct. These numerical techniques require 3D human models; however, due to the high complexity and the variety of tissues in human body, one may ask what level of complexity is sufficient to ensure reliable simulation results. In this article, we present comparisons between homogeneous and more-realistic heterogeneous human phantoms. The objective of this work is to provide a performance analysis for both phantoms on the computed SAR levels.
