HIGH TEMPERATURE SUPERCONDUCTOR TUNABLE FILTER

摘要

A tunable filter having a fixed substrate (20), first and second plates (10, 15) comprising a high temperature superconducting material is fixed on the substrate. A movable substrate (35) includes a mechanical driver (70) attach ed to the fixed and movable substrates. A floating plate (30) of a high temperature superconducting material is fixed to the movable substrate. The floating plate and the first and second plates are arranged to define a gap (50) therebetween, and wherein the gap is varied by length changes effected by the mechanical driver.
