Abstract : The purpose of the work is to develop an electrodynamic equation of state for man adequate to describe power deposition in humans exposed to high-frequency (HF) electromagnetic fields. Further, the dissipation of this deposited energy by known models of thermal transfer is to be utilized to predict physiologic responses and burdens of persons so exposed. Because several thermal models are extant which have been shown to correlate with experimental observation, the authors began by adding radio frequency (RF) power as a thermal load in these equation sets (sections II and III). Electromagentic equations of state are developed in section IV, followed by prediction of power transfer from fields in section V. The head, as a special case, is treated in section VI, and initial attempts to develop a more realistic electrodynamic model are described in section VII.
