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.
