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 efficient method-of-moments formulation is proposed for the analysis of planar structures in the presence of azimuthally symmetric fields. Boundary integral equations are derived for TM and TE polarizations, assuming as a reference structure a metal plate with a finite number of concentric annular slots placed above a stratified medium. The equations are discretized with a Galerkin testing scheme in the Fourier-Bessel domain, adopting suitable sub-domain basis functions that ensure a very rapid convergence of the involved spectral integrals. Numerical validation is provided by comparison with state-of-art simulation software, considering planar antennas with omnidirectional radiation patterns, in order to show the accuracy of the proposed formulation.
