A study of changes to specific absorption rates in the human eye close to perfectly conducting spectacles within the radio frequency range 1.5 to 3.0 GHz
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
