circles), is shown in Fig. 4. The theoretical dependence for the first Fiske step amplitude on field B$_{‖}$ was numerically computed from Eq. (4) and Eq. (5) in the absence of Abrikosov vortices. The value of the parameter γ = 1 . 1 × 10 10 s − 1 provides a best fitting of ex- perimental data. Similar value of γ can be extracted from the I - V curves where the Fiske resonances were suppressed. The agreement with the theoretical analysis is excellent even for the second and third lobes. In the Ref. [27] a similar theoretical analysis of the Fiske resonances of a junction without Abrikosov vortices has been carried out. However, in the equation determining the amplitude a of electromagnetic waves the term of J$_{1}$ was omitted. 

Taking into account this term one can get a better agreement with experimental data.
