On switching the current-phase dependence of Josephson contacts from harmonic mode to anharmonic mode
Main Article Content
Abstract
The question of current - phase dependence switching for Josephson contacts (JC) from harmonic mode to anharmonic one is considered. The equivalent structure of JC in anharmonic mode is represented as serial connected harmonic junctions. The features of JC in anharmonic a mode are interpreted using the
equivalent structure
