Un diagramme de dispersion est utile pour interpréter les caractéristiques d'une structure périodique. En particulier, la région des ondes rapides, où l'onde rayonne, et la région des ondes lentes, où l'onde est guidée, peuvent être déterminées à partir du diagramme de dispersion. Une ligne de transmission (TL) composite droite/gauche (CRLH) à commande électronique a été précédemment proposée et utilisée comme antenne à ondes de fuite (LW) fonctionnant dans la région des ondes rapides. Cependant, étant donné qu’une application à ondes guidées fonctionne dans la région des ondes lentes, il est utile d’étudier les effets des ondes lentes du TL proposé. Dans cet article, le diagramme de dispersion est utilisé pour étudier le facteur d'onde lente (SWF), nécessaire à la compréhension des opérations à ondes rapides et lentes. De plus, les caractéristiques de fréquence sont mesurées pour trouver les fréquences de coupure dans les régions LH et RH. Sur la base de résultats expérimentaux, on observe à une fréquence fixe, 2.6 GHz, que la phase d'une structure proposée à 6 cellules peut être modifiée jusqu'à 280

Abstract: A dispersion diagram is useful in interpreting the characteristics of a periodic structure. In particular, the fast-wave region, where the wave is radiating, and the slow-wave region, where the wave is guided, can be determined from the dispersion diagram. An electronically-controlled composite right/left-handed (CRLH) transmission line (TL) was previously proposed and utilized as a leaky-wave (LW) antenna operating in the fast-wave region. However, since a guided-wave application operates in the slow-wave region, it is meaningful to study slow-wave effects of the proposed TL. In this paper, the dispersion diagram is used to investigate the slow-wave factor (SWF), which is necessary to understand the fast/slow-wave operations. Furthermore, the frequency characteristics are measured to find the cut-off frequencies in the LH and RH regions. Based on experimental results, it is observed at a fixed frequency, 2.6-GHz, that the phase of a proposed 6-cell structure can be changed by up to 280
