US Patent:

51008688, Mar 31, 1992
Filed:

Jan 11, 1991
Appl. No.:

7/640261
Inventors:

Robert L. Snyder - Alfred NY
Allen M. Hermann - Golden CO
Xingwu Wang - Alfred NY
Hongmin Duan - Boulder CO
Jemmy Hao - Alfred NY
Assignee:

Alfred University Inc. - Alfred NY
University of Colorado Foundation, Inc. - Alfred NY
International Classification:

H01L 3912
B05D 304
B05D 302
C23C 410
US Classification:

505 1
Abstract:

A two-step process for the preparation of a thallium-containing superconductive film is described. In the first step of this process, an aerosol mist containing reactants necessary to produce a calcium/barium/strontium/copper precursor material is provided. This mist is subjected to radio-frequency radiation while in the plasma region, and it thereafter is deposited onto an electrically grounded substrate. In the second step of the process, the coated substrate is contacted with thallium-containing vapor.

Tuneable Microwave Devices Including Fringe Effect Capacitor Incorporating Ferroelectric Films

US Patent:

57211949, Feb 24, 1998
Filed:

Jun 7, 1995
Appl. No.:

8/480164
Inventors:

Robert M. Yandrofski - Littleton CO
John Charles Price - Boulder CO
Frank Barnes - Boulder CO
Allen M. Hermann - Golden CO
James Floyd Scott - Boulder CO
Assignee:

Superconducting Core Technologies, Inc. - Denver CO
University Research Corporation - Boulder CO
International Classification:

H01B 1202
H01G 706
US Classification:

505210
Abstract:

The present invention relates to a tuneable fringe effect capacitor for conducting radio frequency energy. The capacitor includes a thin film of ferroelectric material, a pair of films of a conductive material deposited on the ferroelectric film with a gap between the films, and a substrate for the ferroelectric material and the conductive films. The capacitance value across the gap is varied by applying a voltage to the ferroelectric material and thereby altering the dielectric constant of the ferroelectric material.

54729351, Dec 5, 1995
Filed:

Dec 1, 1992
Appl. No.:

7/983632
Inventors:

Robert M. Yandrofski - Littleton CO
John C. Price - Boulder CO
Frank Barnes - Boulder CO
Allen M. Hermann - Golden CO
James F. Scott - Boulder CO
International Classification:

H01P 118
H01P 900
H03H 1116
H01B 1202
US Classification:

505210
Abstract:

The disclosure relates to ferroelectric and superconducting thin films used in combination to produce low-loss passive microwave and millimeter wave devices which are frequency tuneable. Various metal oxide superconducting and ferroelectric thin films can be deposited in numerous multilayer geometries via a variety of deposition techniques to produce devices which can manipulate microwave and millimeter wave signals through the application of voltage bias signals across the ferroelectric films. Numerous superconducting microwave and millimeter wave devices, including delay lines, phase shifters, resonators, oscillators, filters, electrically-small antennas, half-loop antennas, directional couplers, patch antennas, and various radiative gratings, are made frequency-tuneable by utilizing voltage-tuneable capacitor structures fabricated from voltage-biased ferroelectric thin films. Tuneable antenna arrays are also disclosed incorporating the combined superconducting and ferroelectric thin film structures and geometries which allow for electrical steering of beam patterns by the application of one or more voltage bias signals to ferroelectric thin film gratings.
