CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn 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.
