Abstract

The reducing specific absorption rate (SAR) with metamaterials attachment is investigated in this paper. The finite-difference time-domain method with lossy-Drude model is adopted in this analysis. The technique of SAR reduction is discussed and the effects of attaching location, distance, and size of metamaterials, perfect electric conductor (PEC), and materials on the SAR reduction are investigated. Metamaterials have achieved a 41.47% reduction of the initial SAR value for the case of 1 gm SAR. These results suggest a guideline to choose various types of metamaterials with the maximum SAR reducing effect for a phone model.
