Résumé

Cet article présente une approche numérique basée sur la technique des différences finies à points centrés dans le domaine temporel pour évaluer les tensions et courants le long d’une ligne non uniforme à structure planaire chargées par des réseaux à éléments quelconques. La précision de la mééthode est améliorée en tenant compte de l’effet de peau grâce à l’approximation de l’impédance interne Z des conducteurs de la ligne. Plusieurs configurations ont été étudiées afin de montrer l’efficacité de cette méthode de calcul sous différents aspects.

Abstract

This paper deals with a computational approach, based upon centered points finite-difference time-domain technique, for evaluating voltages and currents along nonuniform planar transmission lines terminated with arbitrary loads. To improve the accuracy of the method, the skin effect has been included into the algorithm by means of the approximation of the conductor internal impedance. Some configurations of nonuniform planar lines have been analyzed in order to show different aspects of the efficiency of this computational procedure.
