Abstract:
In this paper, reducing Speci¯c Absorption Rate (SAR) with ferrite sheet attachment is investigated. The ¯nite-di®erence time-domain method with Lossy-Drude model is adopted in this study. The methodology of SAR reduction is addressed and then the e®ects of attaching location, distance, size and material properties of ferrite sheet on the SAR reduction are investigated. Computational results show that the SAR averaging over 10gm was better than that for 1gm and SAR reduction of 57.75% is achieved for SAR 10 gm. These results show the way to choose a ferrite sheet with the maximum SAR reducing e®ect for phone model
