Résumé
Cet article présente une modélisation des lignes microrubans supraconductrices couplées déposées sur des substrats diélectriques bianisotropes par la méthode de Galerkin dans le domaine spectral. Les variations de la permittivité effective pour les modes pair et impair et du facteur de couplage en fonction de certains paramètres primordiaux tels que la température du matériau supraconducteur, la distance entre les deux lignes et l’angle de déviation des axes optiques du matériau diélectrique par rapport aux axes de coordonnées sont étudiées. La validation des résultats numériques est effectuée par une comparaison avec ceux de la littérature.
Abstract
In this paper, we model high temperature superconducting coupled microstrip lines printed on bi-anisotropic substrates by the spectral domain Galerkin method. Hence, we have determined the behavior of the effective permittivity for the odd and even modes and the coupling coefficient as a function of several parameters characterizing superconductivity and bi-anisotropy and the geometry of this structure, such as the superconductor material temperature, the distance between the two lines and the optical deviation angles of the dielectric substrates. The validation of the numerical results has been carried out by comparisons with the bibliographic results.
