Abstract

A modified Fiske step model for Josephson tunneling states that includes a spatial variation of the dc Josephson current is studied. This spatial variation is due to the external current injected from the junction edges. The new model can explain both the Fiske step and zero-field current step (ZFCS) on an equal footing and can account for the symmetric mode recently obtained by one of the present authors (Chang) and his co-workers using computer simulation.
