Magnetic field and current distributions in a system of superconductor microstrip lines

Inductance matrix, current distributions and magnetic field structure for a system of coupled super conductor transmission lines has been calculated by a variational energy method. The influence of the superconducting character, the line geometries and the dielectric thickness on the current and magnetic field distributions have been shown. The coupling between the different lines produces induced currents, superposed on the exciting currents. The real current distribution and the magnetic field at any point determinated by considering this coupling, allow us to optimize the design of superconducting transformers in microstrip technology.
