Characterization of the Specific Absorption Rate of the Cell Phone in the Human Head, Using the LN-FDTD Method. Journal of Engineering and Technology for Industrial Applications (JETIA), Manaus, v. 1, n. 1, p. 61-66, mar. 2015. ISSN 2447-0228.https://rigalileo.itegam.org.br/handle/123456789/1030This work investigates the absorption of electromagnetic energy in biological tissues of the human head from cell phones in the 900MHz band, and the development of a program to calculate the Specific Absorption Rate (SAR) in the user's head. The Local Non-Orthogonal Finite-Difference Time Domain (LN-FDTD) method is implemented, using the Uniaxial Perfectly-Matched Layer (UPML), and the results are compared with existing literature. Findings show that SAR values for 1W and 0.6W exceed safety limits set by international agencies, while 0.25W complies with established standards.pdf.Cell phoneSpecific Absorption Rate (SAR)LN-FDTD methodNon-ionizing radiationElectromagnetic energy absorptionArtigoEngenharia Elétrica
