Effect of tongue jewellery and orthodontist metallic braces on the SAR due to mobile phones in different anatomical human head models including children WhittowWilliam EdwardsRobert PanagamuwaChinthana VardaxoglouJ. C. 2008 This paper has used the Finite-difference Time-domain (FDTD) computer simulation technique to investigate Specific Absorption Rates (SAR) in different human head models with metallic jewellery. A dipole excitation has been placed in front of the nose of 4 anatomical heads including a 5 year old and a 12 year old child’s head. Metallic tongue jewellery and orthodontist metallic braces were added to the models and the SAR was investigated over a range of communication frequencies.
