Application of huygens subgridding technique to human body modelling

The modelling of media with high relative permittivity requires a spatial resolution finer than the one imposed by geometrical constraints. Such materials can be modelled efficiently in subgridding schemes. The ability of 1D HSG-FDTD to handle high meshing ratio allows the successful numerical modelling of a human body. This is the first step towards 3D modelling. Future work will target the efficient and accurate numerical modelling of the human body in 3D using HSG-FDTD.
