ZAMORANO, M.  e  TORRES-SILVA, H.. SAR inducido en un modelo bioplasmático quiral por radiación de teléfonos celulares. Rev. mex. fis. [online]. 2005, vol.51, n.2, pp.209-216. ISSN 0035-001X.

An electrodynamics model formed by chiral bioplasma, which represents the human head inner structure and makes possible to analyze its behavior when it is radiated by a microwave electromagnetic field from cellular phones is presented. The finite difference time domain, FDTD, numeric technique is used, which allows simulation of the electromagnetic fields, deduced with Maxwell equations and to simulate the specific absorption rate, SAR. The results show the SAR behavior in function of input power, antenna impedance and the chirality factor. More important conclusion of our work is that, in considering the chiral factor of propagating media in the proposed model, the human head absorption of the electromagnetic fields from cellular phones is stronger, so the SAR coefficient may be 68% higher than classical model, for the standard values of chiral factor.
