Specific absorption rate analysis using metal attachment

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. Analiza parametra SAR pri uporabi kovinske zaščite Kjučne besede: SAR, prenosni telefon, kovinski nastavek, zmanjšanje SAR Izvleček: V članku analiziramo vpliv kovinskega nastavka na zmanjšanje vrednosti parametra SAR. Raziščemo vpliv položaja, velikosti in razdalje le-tega na zmanjšanje SAR. Še poseben napredek smo dosegli v primeru 1gm SAR. Rezultati nam služijo kot smernica pri izbiri različnih vrst kovinskih materialov, ki najbolj vplivajo na zmanjšanje SAR pri uporabi prenosnega telefona.
