The analysis of nonlinear effects in superconducting microstrip resonators

This paper considers nonlinear effects in high-Tc superconducting microstrip resonators which are defined by nonlinear properties of the surface impedance of such superconductors. Using nonlinear boundary conditions, the paper offers a correct mathematical resonator model with conductors of arbitrary configuration. The modeling results for a transmission-type cavity with capacitive coupling for different levels of entrance influence are given.
