Inclusion of frequency dependency in the huygens subgridding FDTD for UWB systems

This paper proposes the methodology to introduce the ability to deal with the frequency dependent materials to the most promising subgridding technique, HSG scheme, based on the first order Debye model for UWB systems. The numerical experiments have proved that the signals propagate through the subgridding without reflection, signals in the non-working region did not leak into the working region and objects in the working region are handled properly.
