Abstract :
The investigation on the changes of Specific Absorption Rate (SAR) inside the head due to metallic straight pin with simple braces added is presented in this paper. The finite integration in time domain (FIT) computer simulation technique was used in this investigation. The head is irradiated by dipole sources in front of the Specific Anthropomorphic Mannequin (SAM) face. Parametric studies show that 1 gram SAR at 900MHz is slightly reduced. However at 1800MHz, it decreased if pin lengths were varied longer than dipole and it can increase if pin is shorter or both has the same length.
