Abstract: Relative changes in specific absorption rates owing to perturbing metallic spectacles in proximity to the face are investigated. A representative electrical property biological matter model with twenty five distinct tissue types based on images of an adult male is used with the FDTD method. Both plane wave and dipole source stimuli are investigated and are used to represent a mobile cellular-enabled personal digital assistant held in front of the face. Results show that metallic spectacles may alter significantly specific absorption rate (SAR) level distributions within the head. The frequency range investigated is 1.5–3.0GHz. Specific attention is given to energy interactions with the eyes. Results are given for several common spectacle frame shapes in addition to whole head energy absorption comparisons. Whole head and single mirrored half head sensitivity data are also presented. A Pareto ranked genetic algorithm (GA) is used to search for the spectacles that cause the highest and lowest SAR in the eye.
