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.
EnglishRadiation from vertical dipole sources placed inside a grounded dielectric slab covered with a thin microstructured metal screen having annular geometry is studied. The screen is represented through a locally homogenized surface impedance dyadic independent of the azimuthal coordinate, hence is a homogenized omnidirectional metasurface. The excited field is also omnidirectional; we propose here both analytical and numerical models for the calculation of its far-field pattern, the former valid for radially constant surface impedances, the latter valid for piecewise-constant impedances.
