dc.description.abstractThis 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.
dc.description.resumoO estudo aborda a absorção de energia eletromagnética em tecidos biológicos da cabeça humana, originada por telefones celulares na banda de 900MHz, e o desenvolvimento de um programa para calcular a Taxa de Absorção Específica (SAR) na cabeça do usuário. O método Local Non-Orthogonal Finite-Difference Time Domain (LN-FDTD) é implementado, utilizando a camada Uniaxial Perfectly-Matched Layer (UPML), e os resultados são comparados com dados da literatura. Os resultados indicam que valores de SAR para potências de 1W e 0,6W excedem os limites de segurança estabelecidos por agências internacionais, enquanto 0,25W está dentro dos padrões.
