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.
EnglishAn approach to solve the scattered field by perfectly conducting cilnders with circular cross-section, and placed below a multilayered medium, under illumination by a line source, is presented. In principle, the interaction of the field scattered by the targets with the multilayer above leads to an infinite number of scattered fields, excited as multiple reflections in each layer by the interfaces. Nevertheless, the developed theoretical formulation is a very compact one, as only two scattered-field contributions are used in each layer, a down-propagating term, described as scattered-reflected field, and an up-propagating one relevant to the scatteredtransmitted field. Suitable basis functions, i.e., cylindrical waves expressed through plane-wave spectra, are employed, which are defined through reflection and transmission coefficients of a multilayered medium. As shown in the numerical implementation, the method can be applied to the modelling of several radar problems of targets in complex environments. For example, the technique can be employed to model buried cylinders in geophysical scenarios, in Ground Penetrating Radar applications. The modelling of scattered field by hidden targets in Through-the-Wall radar surveys is another possible field of use. The multilayer may, ineeded, model a stratified masonry, but also a room hidding a target in a buildings’ interior.
