This paper examines the effects of metallic semirimmed
spectacles on the specific absorption rate (SAR) inside
the head when illuminated by a frontal dipole source
representing a PDA held in front of the face. The frequency
considered is 900MHz. Both children’s and adult’s spectacles are
investigated using the Loughborough SAM (Specific
Anthropomorphic Mannequin) head incorporated into a DASY4
robot measurement system. The spectacles are tested with and
without their arms. For comparison, simulations of the SAM
head using FDTD have been conducted. Results show children’s
semi-rimmed spectacles may be resonant at 900MHz and may
have a focusing effect that redistributes the SAR in the head.
