Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishIn this work we treat in detail the acceleration of the freespace scalar Green’s function in three dimensional (3-D) structures with one dimensional (1-D) periodicity. We analyze the methods able to deal with a complex phase shift, necessary to study complex waves in periodic structures. We present a spectral Kummer-Poisson’s decomposition; then we extend the application of the Ewald’s method by performing an optimization of the relevant splitting parameter, and we also find an integral representation. Comparisons among the various acceleration methods are performed, thus providing fundamental information on their actual efficiency.
