Méthode FDTD conforme appliquée au calcul du DAS avec homogénéisation utilisant les caractéristiques des tissus humains

Abstract : The constant development of communication systems raises concerns about the influence of electromagnetic waves on human body. Existing legislation helps to reassure population, but daily exposure, often multi-source, involves questions about these new types of use. The Time Domain Finite Difference (FDTD) method allows accurate assessment of the level of exposure described in this manuscript. However, this method has limitations if it is desired to represent structures with curvatures due to the use of orthogonal meshes. This manuscript is a contribution to the problem by developing a conformal FDTD method whose meshes follow the shape of the objects to be modeled. Even so, some existing FDTD compliant methods in the literature will be presented beforehand. In this study, particular attention will be paid to the validation of the method developed through several different types of meshes and comparing results obtained with HFSS and conventional FDTD. The specific absorption rate (SAR) will also be calculated by homogenizing human tissues by volume weighting. This will reduce computing time
