WHITTOW, EDWARDS and COOK, 2003. A study of changes to specific absorption rates in the human eye close to perfectly conducting spectacles within radio frequency range 1.5 to 3.0GHZ. IN: 12th International Conference on Antennas and Propagation, Exeter, UK, 2003, pp. 300-303.
This paper investigates changes in specific absorption
rates due to metallic spectacles in close proximity with a
head of representative electrical properties. Here, the
FDTD method is used with a Z directed plane wave to
simulate a personal digital assistant held in front of the
face. Results confirm that metallic spectacles can
significantly change SAR levels at frequencies between
1.5 and 3GHz. Specific attention is given to the energy
interaction in the eyes and the nose. Results are given
for several common spectacle frame shapes as well as
whole head energy absorption comparisons.
