Effect of tongue jewellery and orthodontist metallic braces on the sar due to mobile phones in different anatomical human head models including children

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.
