We report on a tunable quasilumped element bandstop resonator using a high-temperature superconductor and a strontium barium titanate bilayer. The application of a bias ¨oltage produces a tuning of the stopband. Also, by comparing measured results with simulation, the dielectric permitti¨ity and los

Superconducting resonator systems with high Q at uhf cata be used to create capacitance probes, transforming mechanical motions into electrical signals. ~-4 To increase the efficiency of such devices it is essential that the resonator system should have not only high Q, but also electrical capacitan
