In this work, Finite Difference-Time Domain (FDTD) calculations of over 1g averaged specific

absorption rate (SAR) in a 2mm resolution head are presented between 500MHz and 2500 MHz. External

electric field levels are derived from computed 1g SAR values, and compared with previous and current IEEE

limits. Results indicate that the presence of metallic wire spectacle, in general, reduces the external electric field

levels. The largest peak localized SAR values averaged over 1g tissue are not found within the safety levels

specified by IEEE for an uncontrolled environment.
