Abstract :
Surface impedance boundary conditions (SIBC) for superconductor layers are provided. These can be used for arbitrary thick conductors from very thin to very thick. A superconducting layer is considered as a TEM transmission line so that the SIBCs can be obtained as the input impedances of an open ended and a short circuited transmission line, respectively. The SIBCs are verified for a microstrip line and a coplanar waveguide made of Niobium on a LaAlO3 substrate.
