Estimating the electromagnetic field effects in biological tissues through the finite-difference time-domain method

This work presents an analysis concerning the effects of iteration between electromagnetic fields and some kinds of biological tissues. In this regard, we design a routine based on the finite-difference time-domain (FDTD) method to estimate the electromagnetic field in 3D environments for biological tissues. Our research of electromagnetic field effects has focused on the concept of specific absorption rate (SAR 1 g and SAR 10 g). The electromagnetic field estimation method presented in this paper allows the evaluation of the desired SAR levels, which from our results, indicate that the SAR levels can be higher than those assigned by the regulatory agencies.
