In this work, an application of the recent Huygens Subgridding (HSG) method to study lossy materials with the ¯nite-di®erence time-domain (FDTD) scheme is presented and a related error analysis discussed. Achieved HSG results showed a good agreement with a full higher-resolution reference guide for di®erent electrical parameter values, indicating a negligible numerical dispersion on the transverse section. Moreover, the increasing decimation factor e®ect has been investigated to evaluate the subgridding accuracy. Findings are of interest in the numerical prediction of planar screens e®ectiveness, material parameters retrieval and microwave spectroscopy.

Abstract

In this work, an application of the recent Huygens Subgridding (HSG) method to study lossy materials with the ¯nite-di®erence time-domain (FDTD) scheme is presented and a related error analysis discussed. Achieved HSG results showed a good agreement with a full higher-resolution reference guide for di®erent electrical parameter values, indicating a negligible numerical dispersion on the transverse section. Moreover, the increasing decimation factor e®ect has been investigated to evaluate the subgridding accuracy. Findings are of interest in the numerical prediction of planar screens e®ectiveness, material parameters retrieval and microwave spectroscopy.
