Abstract
Specific absorption rate (SAR) reduction with metal attachment is analysed in this paper. The SAR reduction technique is discussed and the effects of attaching location, distance, and size of metal on the SAR reduction are investigated. The remarkable improvement has been achieved for SAR reduction of the initial SAR value for the case of 1 gm SAR. These results suggest a guideline to choose various types of metals with the maximum SAR reducing effect for a portable telephone.
