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.
EnglishArtificial dielectrics with a continuous spatial variation of the electromagnetic parameters used as high-pass filters are presented. First the theoretical model for the Propagation of the TFM field inside these materials is carried out by means of the nonuniform transmission lines. Second by using a generalization of the nonuniform transmission line theory a new, reflection coefficient closed form, that can be useful both in analysis and in synthesis purposes because of its easiness, speed and accuracy, is obtained Thus, a new design technique for microwave filters using such inhomogeneous materials, based on the new reflection coefficient closed form, is proposed Finally some numerical results that show both the filtering behavior of the inhomogeneous media and the capabilities of the new synthesis method are presented.
