the correlation area for Abrikosov vortices as where the sign < .... > means the averaged value over the random positions of Abrikosov vortices. The correlation area σ ( k ) depends on the density of misaligned Abrikosov vortices n$_{A}$ , the misalignment length δ , and the wave vector k that, in turn, is determined by an externally applied magnetic field parallel to the junction plane B$_{‖}$ . For the particular case of a circular junction the σ ( k ) has been found in [16, 17, 20], and in the absence of B$_{‖}$ where L is the radius of the circular junction. It has been obtained in [16, 17, 20] that the critical current of the Josephson junction with randomly distributed misaligned Abrikosov vortices is determined by the correlation area σ ( k ) as Thus, in the absence of B$_{‖}$ as the critical current reaches the maximum, we obtain a strong decrease of the critical current I$_{c}$ with the Abrikosov vortices density n$_{A}$ : where I$_{c}$$_{0}$ is the critical current in the absence of Abrikosov vortices. Next, we turn to the analysis of Eqs. (4) and (5) determining the amplitudes of Fiske resonances. First, we notice that even in the absence of k$_{0}$ (or B$_{‖}$ ) the amplitudes of Fiske resonances I ( n ) F are not zero. However, the magnitudes of Fiske steps can be increased by tuning of B$_{‖}$ . The maximum values of I ( n ) F reach as the condition k$_{n}$ = k$_{0}$ is satisfied. In the following we will assume that the correlation area σ is small, i.e. σ ≪ S . Using this assump- tion we express the maximum amplitudes of Fiske resonances I ( n ) F through a single parameter σ (0) = σ . Indeed, in the limit as σ is small or more precisely σ ≪ S ( λ 2 $_{J}$γω 0 c 2 0 ) 2 = σ $^{∗}$, the amplitudes a$_{n}$ are small, and expanding the Bessel function over a small argument a$_{n}$ we obtain In this regime I (1) F is proportional to σ and displays a strong exponential decrease with n$_{A}$ .
