High order DGTD- Maxwell solver for numerical dosimetry studies

Participants : Stéphane Lanteri, Joe Wiart [ WHIST Laboratory, Orange Labs, Issy-les-Moulineaux ] .

The objective of this research grant with the WHIST (Wave Human Interactions and Telecommunications) Laboratory at Orange Labs in Issy-les-Moulineaux is the adaptation of a high order DGTD- method on tetrahedral meshes developed in the team and its application to numerical dosimetry studies in the context of human exposure to electromagnetic waves emitted from wireless systems. These studies involve realistic geometrical models of human tissues built from medical images. In this context, a specific topic addressed in this work deals with the numerical assessment of a strategy combining a refinement/coarsening of the discretization of tissue interfaces with a local definition of the approximation order, and its impact on the conservativity of the localization and amplitude of the maximum local SAR (Specific Absorption Rate) in the tissues.
