Power Dependent Impedance of High Temperature Superconductor Thin Films: Relation to Harmonic Generation

December 31, 2001

Author(s)

James Booth, Leila R. Vale, Ronald H. Ono, John H. Claassen

Comparitive Studies of the Microwave Nonlinearities in High Temperature Superconducting Thin Films and Devices

August 1, 2001

Author(s)

James Booth, Leila R. Vale, Ronald H. Ono

We have studied nonlinear, power-dependent, behavior of high temperature superconducting thin films, transmission lines, and resonators. Here we present measurements of a material-dependent parameter, the scaling current density J 0, which represents the

Modeling Linear and Nonlinear Inductive Effects in Superconductiong Planar Circuits

August 1, 2001

James Booth, Christopher L. Holloway, Edward Kuester

On-Wafer Measurements of Nonlinear Effects in High Temperature Superconductors

March 1, 2001

Author(s)

James Booth, Leila R. Vale, Ronald H. Ono

We present the results of comprehensive on-wafer microwave probe station measurements of the nonlinear properties of coplanar waveguide devices patterned from HTS thin films. We introduce a sequence of measurements and analysis that is designed to describe

Broadband Determination of Microwave Permittivity and Loss in Tunable Dielectric Thin Film Materials

October 1, 2000

Author(s)

James Booth, Leila R. Vale, Ronald H. Ono

We demonstrate a new method for determining the frequency-dependent dielectric properties of thin-film materials at microwave frequencies using coplanar waveguide (CPW) transmission line measurements. The technique makes use of the complex propagation

Coplanar Transmission Lines with Meandering Center Conductors in Y-Ba-Cu-O/Au Bilayers

December 31, 1999

Author(s)

C Weber, Ronald H. Ono, James Booth, Leila R. Vale, Samuel Benz, A. M. Klushin, H. Kohlstedt, C. Buchal, R. Semerad

We have investigated both conventional and meandering coplanar microwave transmission lines patterned in Y-Ba-Cu-O/Au bilayers on yttria-stablized zirconia and sapphire substrates. Within the meandering waveguides, the gentre conductor was deformed from a
