Microwave Power Handling in Engineered Yba 2 Cu 3 O^d6-d Grain Boundaries

October 12, 1998
Author(s)
Y. M. Habib, D. E. Oates, G. Dresselhaus, M. Dresselhaus, Leila R. Vale, Ronald H. Ono
Microwave-frequency (rf) power-dependence measurements performed on thin-film Yba 2Cu 3O^d7-δ grain boundaries engineered on sapphire bicrystal substrates with misorientation angles of θ=20, 50, 100, and 240 are presented. The data are compared to

Measurements and Modeling of the Microwave Impedance in High-T c Grain-Boundary Josephson Junctions: Fluxon Generation and RF Josephson-Vortex Dynamics

June 1, 1998
Author(s)
Y. M. Habib, C. J. Lehner, D. E. Oates, Leila R. Vale, Ronald H. Ono, G. Dresselhaus, M. Dresselhaus
Measurements and modeling of the microwave-frequency (rf) power dependence of the impedance in Y-Ba-Cu-O thin-film grain-boundary Josephson junctions (jj's) are presented. Microwave impedance measurements were performed using a stripline resonator with an

Active Cavity Radiometer Based on High-TC Superconductors

January 1, 1998
Author(s)
Joseph P. Rice, Raju V. Datla, Leila R. Vale, David A. Rudman, M L. Sing, D Robbes
To implement the detector-based radiometric scale in the new Medium Background infrared [MBIR] facility at the National Institute of Standards and Technology [NIST], we have developed an electrical substitution cavity radiometer that can be operated at
