Relationship between temperature rises with SAR in a head tissue in bandwidth exposure

In this paper we suppose to discuss recent results of study influence of Electromagnetic (EM) exposure of mobile phones radiation on the user. This is the part of topic: “Developing a Thermal Exemptions Rationale for Low-Power Transmitters”. Particularly, we present results of computer simulation of the users head exposure via radiation of electrically small and resonant length antennas. Compare and contrast threshold power with temperature increase in tissue and SAR. Investigate the relationship between temperature rise with SAR and between temperature rise and bandwidth/efficiency.
