Note 1 to entry: For a transmission line the phase coefficient is the limit of the quotient of the phase change of a field quantity between two points on the axis by the distance between the points, when this distance tends to zero.
Note 1 à l'article: Pour une ligne de transmission, le déphasage linéique est la limite du quotient de la variation de phase d'une grandeur de champ entre deux points sur l'axe par la distance des points, lorsque cette distance tend vers zéro.
