SAR variations in the face due to semi-rimmed spectacles and polarized sources at GSM900 and GSM1800

This paper presents experimental and simulated results from a study looking at the effects of semi-rimmed spectacles on the specific absorption rates (SAR) inside the head. Measurements were carried out using a modified specific anthropomorphic mannequin (SAM) phantom head incorporated into a DASY4. 1g SAR was recorded for 14 different semi-rimmed spectacles using CW dipole sources at 900MHz and 1800MHz. Simulations have also been conducted using the digitised SAM head and a pair of spectacles.
