  "The non-contact broadband transmission line flip-chip spectroscopy technique
is utilized to probe resonances of mm-sized square kinetic planar resonators
made from strongly disordered molybdenum carbide films, in the GHz frequency
range. The temperature dependence of the resonances was analyzed by the complex
conductivity of disordered superconductor, as proposed in Ref. arXiv:1407.2402
, which involves the Dynes superconducting density of states. The obtained
Dynes broadening parameters relate reasonably to the ones estimated from
scanning tunneling spectroscopy measurements. The eigenmodes of the kinetic
planar 2D resonator were visualized by EM model in Sonnet software. The proper
understanding of the nature of these resonances can help to eliminate them, or
utilize them e.g. as filters."
