Um método de domínio de tempo de diferenças finitas multi-grade (FDTD) foi aplicado para análise de dosimetria numérica na cabeça humana para terminais portáteis na banda de 5 GHz. Ao aplicar grades finas de FDTD aos volumes na cabeça humana onde ocorre a maior absorção eletromagnética (EM) e grades grosseiras aos volumes restantes da cabeça, a avaliação da taxa de absorção específica de pico espacial (SAR) foi alcançada com menos memória computacional e tempo. A precisão da aplicação do método FDTD multi-grade à avaliação do SAR de pico espacial foi verificada em comparação com os resultados obtidos do método usual de grade uniforme e, em seguida, os SARs de pico espacial para três situações típicas de uma pessoa usando uma banda de 5.2 GHz terminal portátil foram calculados em conjunto com um modelo de cabeça humana com base anatômica.

Abstract: A multi-grid finite-difference time-domain (FDTD) method was applied for numerical dosimetry analysis in the human head for 5 GHz band portable terminals. By applying fine FDTD grids to the volumes in the human head where the highest electromagnetic (EM) absorption occurs and coarse grids to the remaining volumes of the head, the spatial peak specific absorption rate (SAR) assessment was achieved with a less computation memory and time. The accuracy of applying the multi-grid FDTD method to the spatial peak SAR assessment was checked in comparison with the results obtained from the usual uniform-grid method, and then the spatial peak SARs for three typical situations of a person using a 5.2 GHz band portable terminal were calculated in conjunction with an anatomically based human head model.
