【 摘 要 】

In this paper, reducing of specific absorption rate (SAR) with materials and metamaterials attachment is investigated. The finite-difference time-domain method with lossy-Drude model is adopted in this study. The methodology of SAR reduction is addressed and the belongings of attaching position, distance, and size of ferrite sheet material properties, perfect electric conductor (PEC), and metamaterials on the SAR reduction are investigated. Materials have achieved a 47.02% reduction of the initial SAR value while metamaterials achieved a reduction of 49.21% respectively for the case of 1 g SAR. These results propose a guideline to decide assorted types of materials and metamaterials with the utmost SAR reducing effect for a phone model.
