A superconducting tunable filter is disclosed that has a center frequency and a bandwidth able to be adjusted separately. The superconducting tunable filter includes a superconducting resonator filter pattern formed on a dielectric substrate; a dielectric or magnetic plate above the resonator filter pattern and having a through-hole; a dielectric or magnetic rod inserted in the through-hole; and a position controller which separately controls the position of the dielectric or magnetic plate and the position of the dielectric or magnetic rod relative to the resonator filter pattern.

Superconducting tunable filter

A superconducting filter device is disclosed that is able to prevent current concentration and improve electrical surface resistance. The superconducting filter device includes a first dielectric substrate, and a bulk superconducting resonator that is embedded in the first dielectric substrate and is formed from a bulk superconducting material.
