Finite-Difference Time-Domain (FDTD) Method with Non-Homogeneous Cells Filled with Voxels Tekbaş, Kenan Berenger, Jean-Pierre FDTD Subcell Voxel Multigrid This work was supported in part by EU Horizon 2020 Research and Innovation Programme under Marie Sklodowska-Curie Action under Grant 101066571. With the objective of reducing the overall number of FDTD cells in applications where the objects of interest are given as sets of voxels, as in bio-electromagnetism, a subcell technique is introduced to allow the FDTD method to account for non-homogeneous cells composed with voxels of different permittivity’s. Numerical experiments with dielectric objects are reported to illustrate the effectiveness and the limitations of the method. 2024-02-16T10:51:10Z 2024-02-16T10:51:10Z 2023-09-15 journal article Published version: Tekbaş, Kenan y Berenger, Jean-Pierre.
