摘要

The paper investigates changes in specific absorption rates due to metal-framed 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 3 GHz. 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.
