Abstract
A portion of the superconductor in a planar resonator made from that superconductor can be switched into the normally conducting state so that its effective lateral dimensions are changed. The special advantage of this planar resonator is that a switchable filter can be constructed very economically based on its planar resonator structure. Since no perturbing bodies are necessary in the field, the invention points the way to a switchable filter with reduced high frequency losses.
