Parametric Effect and Surface Impedance of Htsc Films at AN Irradiation

Processes in a modulation amplifier on a high temperature superconducting film with nonlinear parametric inductance and active resistance are theoretically examined. The expression is obtained in this paper for the average power on the inductance. A possibility of a parametric regeneration on the modulation frequency of the surface impedance of a HTSC film offers at the irradiation of the latter by an optical radiation modulated on the intensity.
