Cet article présente une approche numérique de l'analyse dans le domaine temporel des coupleurs à N-branches. L'approche est basée sur la méthode de différence centrale modifiée (MCD) combinée à des traitements de limites internes, qui consistent en la matrice de diffusion dans le domaine temporel pour la discontinuité de jonction à trois ports. Le comportement de propagation du signal, y compris les réflexions multiples sur le coupleur à N branches avec et sans perte de ligne, est analysé et démontré dans le domaine temporel. De plus, les paramètres S obtenus à partir des réponses impulsionnelles gaussiennes des coupleurs directionnels à N branches sont présentés. Les résultats simulés sont en bon accord avec ceux du simulateur commercial.

Abstract: This paper presents a numerical approach to the time-domain analysis of N-branch-line couplers. The approach is based on the modified central difference (MCD) method combined with internal boundary treatments, which consist of the time-domain scattering matrix for the three-port junction discontinuity. The behavior of the signal propagation including multiple reflections on the N-branch-line coupler with and without line loss is analyzed and demonstrated in the time domain. Additionally, the S-parameters obtained from Gaussian pulse responses of the N-branch-line directional couplers are shown. The simulated results are in good agreement with those of the commercial simulator.
