The kinetic inductance (KI) of superconducting devices can be exploited for reducing the footprint of linear elements as well as for introducing nonlinearity to the circuit. We characterize the linear and nonlinear properties of a multimode resonator fabricated from amorphous tungsten silicide (WSi) with a fundamental frequency of ($f_1 = 172$) MHz. We show how the multimode structure of the device can be used to extract the different quality factors and to aid the nonlinear characterization…
