Plasma frequency in Josephson junctions with a non-sinusoidal current-phase relation

摘要

This paper shows the increase of the Josephson junctions plasma frequency with non-sinusoidal current-phase relation and the change of the plasma frequency at switching current-phase relation of Josephson systems from a harmonic mode to an anharmonic. The results may be useful for the determination of the plasma frequency of the Josephson Φ -junction.
