Temperature dependencies of frequency characteristics of HTSC RLC curcuit

Analytical expressions of temperature dependencies of magnitude–frequency and phase–frequency characteristics of a HTSC RLC parallel circuit are obtained, where the resistance and inductance are non-linearly depended on the optical signal modulated by the intensity. It is shown that the magnitude–frequency and phase–frequency characteristics of circuits can be controlled by choosing the parameters of the HTSC thin film and optical ‘‘pump’’.
