Membrane supported coplanar waveguides are needed for low-dispersive and low-loss millimeter and submillimeter waves circuits. This paper presents electromagnetic simulations and experimental results for the effective permittivity of membrane supported transmission lines and demonstrate the necessity of computer aided design techniques in the ...

Abstract High quality YBa2Cu3O7−x (YBCO) thin films were grown on LaAlO3 by de-magnetron sputtering. The films showed critical temperatures of 91 K and critical current densities well beyond 106 A/cm2 at 77 K. From 200 nm thick films coplanar waveguide resonators were patterned with characteristic impedances between 40 and 50 Ω.

21st European Microwave Conference, 1991, 1991
A self-adaptive mesh technique is presented for the finite element (FEM) full-wave analysis of microwave transmission lines and waveguiding structures. It provides an accurate FEM program with automatic well adapted mesh generation, starting from a coarse mesh, refined step by step, depending on local error indicators. Results are shown.

We report on the application of Si and Al ion-implantation patterning to the fabrication of low-loss microwave transmission lines in high-temperature superconductor (HTS) thin films. Using this technique, we have fabricated coplanar waveguide (CPW) transmission lines in YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// (YBCO) thin films deposited on LaAlO/sub 3/
