Abstract

An accurate and fast algorithm is proposed to evaluate the specific absorption rate (SAR) in an anatomically realistic human head model exposed to a wideband antenna. The algorithm is based on the discontinuous Galerkin time domain (DGTD) method using hybrid meshes. Hexahedral and tetrahedral meshes are used, respectively, to model the human head with a voxel data format and the wideband antenna with curved and thin structures. The hexahedral and tetrahedral meshes are connected with pyramidal meshes. The Debye model is used to model the dispersive property of the human head tissues. The efficiency of the proposed algorithm is demonstrated by numerical results for SAR in CMODEL exposed to an ultra-wideband antenna.
