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.
EnglishA transmission-line model is developed for the analysis of planar waveguides including wire-medium slabs with vertically aligned wires. The developed network formalism allows for an effective determination of the modal dispersion equation via transverse resonance, as opposed to the more cumbersome field-matching approach. Closed and open parallel-plate waveguides loaded with wire medium are considered. The suppression of undesired TEM-mode propagation and the possible achievement of a unimodal regime are investigated. Numerical results, validated also against state-of-the-art simulation software, confirm the accuracy and effectiveness of the proposed approach. Dispersion relations of complex modes are obtained for a class of leaky-wave antennas based on open wire-medium layered structures covered by partially reflecting screens.
