This paper investigates relative changes in specific absorption rates due to perturbing metallic spectacles in proximity to the face. A representative electrical property biological matter model with 25 distinct tissue types based on magnetic resonance imaging data is used with the finite-difference time-domain method. Both plane wave and dipole stimuli are investigated and are used to represent an excitation from the front of the head. The frequency range investigated is 1.5 to 3.0 GHz. Results show that metallic spectacles may significantly alter SAR level distributions within the head. Specific attention is given to energy interactions with the eyes. Results are given for several common spectacle frame shapes.
