GARCIA, Carina C.  and  ZAMORANO, Mario L.. Determination of the specific absorption rate (SAR) in WiFi and Wi-Max systems by means of a chiral bioplasma model. Inf. tecnol. [online]. 2020, vol.31, n.2, pp.133-140. ISSN 0718-0764.

A chiral-bioplasma model that characterizes the human head and analyzes its behavior when it is radiated by the microwave of wireless systems is presented. The technique of the method of finite differences in the domain of time allows numerical calculation of electromagnetic fields and simulates the specific absorption rate. The results were obtained for section 35 of the magnetic resonance imaging model. The most important conclusion of our work is that, considering that the brain tissue is a chiral bioplasma, there is greater absorption, compared to the classic models, of the microwave radiation emitted by the WiFi and Wi-Max systems.

Keywords : specific absorption rate; SAR; WiFi; Wi-Max; chiral model.
