Variations in calculated whole body SAR for different ground coupling models

This paper studies the effects of various ground conditions on whole body specific absorption rate (SAR) calculations. As part of ongoing research assessing human exposure in the near-field of BBC World Service HF transmitter sites, the work in this paper considers how different modelling implementations of ground conditions alter the calculated whole body SAR for a human standing within a vertically or horizontally polarised 6 MHz electric field. The models of a heterogeneous human phantom developed for this paper are compared to, and extend, results previously published by the UK Healthy Protection Agency (HPA).
