Abstract:
1. A superconducting tunable filter, comprising: a resonator filter pattern that is formed from a superconducting material and is formed on a dielectric substrate; a dielectric or magnetic plate that is arranged above the resonator filter pattern and has a through-hole; a dielectric or magnetic rod that is inserted in the through-hole; and a position controller that separately controls a position of the dielectric or magnetic plate and a position of the dielectric or magnetic rod relative to the resonator filter pattern, wherein the resonator filter pattern is an arrangement pattern including plural disk-like resonators arranged adjacent to each other, and the through-hole is located between adjacent two of the adjacent disk-like resonators or between the disk-like resonators and an input-output feeder for transmitting signals to the disk-like resonators.
