Phenomenological model of microwave electrodynamics of high-T-c superconductor metal oxides

Phenomenological model of microwave electrodynamics of the metal oxide high-T-c superconductors (HTSC) is presented. The model takes into account the effects of the finite complex dielectric permittivity and of the local (acting) electric fields in semiclassical interpretation of the current carrier dynamics. The effects should be significant due to the layered structure and the metal-insulator type instability of HTSC metal oxides. Microwave electrodynamics of the superconducting state of HTSC is described on the base of the general two-fluid principles. The full expressions for the complex dielectric permittivity and for the surface impedance are derived and used to relate the current carrier parameters with the data of microwave measurements.
