Abstract :
This paper concerns numerical computation of the specific absorption rate (SAR) of a human body exposed to a random field. The model has been taken from the ldquoVisible Human Body Projectrdquo. It is placed in a reverberation chamber (RC) whose internal field is simulated using the plane wave integral representation and which is numerically solved by a superposition of N plane waves repeated M times. This method is largely used for the electromagnetic compatibility (EMC) measurements and is also applied to calculate the absorbed power, and subsequently, temperature distribution of an object heated in an RC. In the present paper it is used to calculate the SAR at various frequencies for the whole human body and for some tissues, thereby recreating an environment which has characteristics very similar to the real environment that bombards us with dangerous radiations coming from different directions, and the field may assume random characteristics.
