Title:
TUNABLE SUPERCONDUCTOR RESONATOR OR FILTER
Document Type and Number:
WIPO Patent Application WO2003079482
Kind Code:
A8
Abstract:
A tunable superconductor apparatus or associated method. The apparatus comprises a coil, a first superconductor film portion, a second superconductor film portion, and an actuator. The first superconductor film portion is electrically coupled to the coil. The second superconductor film portion is inductively coupled to the first superconductor film portion. Displacement of the second superconductor film portion relative to the first superconductor film portion changes the capacitance between the second superconductor film portion and the first superconductor film portion. The actuator is capable of relatively displacing the second superconductor film portion and the first superconductor film portion to change a resonant frequency of the tunable superconductor apparatus. In one aspect, the actuator includes a Micro-Electromechanical (MEM) component or a mini electric-motor component that have the capability of relatively displacing the second superconductor film portion and the first superconductor film portion. The superconductor apparatus is configured, for example, as a resonator or as a filter in the frequency range of 1 MHz to 10 GHz.
