Inductance, current distribution and magnetic field for a set of superconducting lines
Description
We determine the free energy of a superconducting network and minimize it by a variational method. We calculate the current density distribution, the structure of the magnetic field and the inductance matrix. The results obtained for a superconducting microstrip line show the edge effects related to the geometry used (width of the strip: 2.5 μm). These effects produce ''cross-talk'' which must be taken into account in integrated Josephson circuit conception. We also show the influence of the London penetration depth on the distribution of the current density in superconductors and on the magnetic field structure in any point of the microstrip line
Abstract (French)
Nous determinons l'energie libre d'un ensemble de lignes supraconductrices et la minimisons par une methode variationnelle. Nous calculons la distribution des courants, la structure du champ magnetique et la matrice inductance du systeme. Les resultats obtenus pour une ligne micro-ruban supraconductrice mettent en evidence les effets de bords lies a la geometrie utilisee (ruban de largeur 2,5 μm). Ces effets peuvent etre a l'origine de couplages parasites dont le role doit etre pris en compte dans la conception de circuits integres realises en technologie Josephson. Nous montrons egalement l'influence des profondeurs de London sur la distribution des courants dans les supraconducteurs et sur la structure du champ magnetique en tous points de la ligneAdditional details
