Characterization of the Specific Absorption Rate of the Cell Phone in the Human Head, Using the LN-FDTD Method

Abstract

In this work we show how the study of the absorption of electromagnetic energy will be approached in biological tissues of the human head, originating from cell phones in a 900MHz band, and the development of a program to calculate the Specific Absorption Rate (SAR) in the cell phone user’s head. The implementation of the Local Non-Orthogonal Finite-Difference Time Domain method is presented (LN-FDTD), and the use of Uniaxial Perfectly-Matched Layer (UPML), comparing the results obtained with the existing results in the literature.
