Summary
The non-linear response near T c and the complex electromagnetic conductivity of YBa2Cu3O7 single crystals at microwave frequencies are explained in the framework of the two-fluid model with the additional hypothesis that the e.m. field modulates the partial concentrations of both normal and superconducting fluids.
