Abstract: A measuring whispering-gallery-mode resonator, comprising: a dielectric resonating body with a rotation axis; a superconducting sample under test, which is mounted to the resonating body; a coupling unit for coupling a measuring waveguide with the resonating body, wherein one side of the resonating body connected with the coupling unit is provided with a first endplate, wherein m coupling holes penetrate through the first endplate, and centers of the m coupling holes are arranged to be evenly spaced along a circle whose center is on the rotation axis; the coupling unit has a feeder line which is a coaxial waveguide, wherein an axis of the coaxial waveguide coincides with the rotation axis, and one end surface of the coaxial waveguide, which is perpendicular to the rotation axis, abuts to the first endplate; and the axial index of operated whispering gallery mode in the resonator is an integer multiple of the number m of the coupling holes.
