Modeling of the human exposure inside a random plane wave field

The speciflc absorption rate (SAR) of a human body exposed to a random fleld inside a reverberation chamber (RC) has been modeled. The exciting fleld is simulated using the plane wave integral representation which is numerically solved by a superposition of N plane waves randomly generated and repeated M times to reproduce the same statistics of an RC. An experimental validation, carried out by means of known saline solutions, conflrms the reliability of this method. The obtained results at various frequencies for the adopted \Visible Human Body" and for some tissues well highlight the absorption percentage. The frequency behavior of the total SAR reveals the resonance of the human body around 75MHz, in spite of the chaotic source.
