Abstract
The influence of high order harmonics (Ik sin kϕ, k > 1) of the current-phase relation I(ϕ) of a short superconducting microbridge on the corresponding rf-induced current-voltage characteristic is studied. For a special non-sinusoidal relation I(ϕ) derived from the model of Baratoff et al., the step-heights are calculated as function of the amplitude of the applied rf-field. An approximation method for the determination of the spectrum Ik of I(ϕ) by means of an evaluation of the given step-structure is discussedKeywords
