摘要
The reducing specific absorption rate with metamaterials attachment is investigated in this article. The finite-difference time-domain method with a lossy-Drude model is adopted in this analysis. The technique of specific absorption rate reduction is discussed, and the effects of attaching location, distance, and size of metamaterials, perfect electric conductor, and materials on the specific absorption rate reduction are investigated. Metamaterials have achieved a 42.12% reduction of the initial specific absorption rate value for the case of 1 gm specific absorption rate and 53.94% reduction for the cases of 10 gm specific absorption rate. These results suggest a guideline to choose various types of metamaterials with the maximum specific absorption rate reducing effect for a phone model.
