Abstract: | The equivalent parameters of a Josephson junction in a microwave SQUID structure are calculated on the basis of relations
obtained as a result of an analysis of the operation of an rf SQUID. This analysis is based on the sawtooth variation of the
voltage on the resonator as a function of the constant flux bias. The quantitative characteristics permit regarding the Josephson
junction as a linear impedance in the rf or microwave circuit, whose real and imaginary parts are controlled by the constant
magnetic flux passing through the SQUID loop.
