Recently, it has been found that the Josephson-vortex flow resistance oscillates as a function of magnetic field when Josephson vortices form a triangular lattice [S. Ooi, T. Mochiku, K. Hirata, Phys. Rev. Lett. 89 (2002) 247002]. To study the effects of the sample boundaries on the Josephson-vortex flow, we have measured the in-plane anisotropy of Josephson-vortex flow resistance. In addition to a strong suppression of the flow resistance for fields parallel to the boundaries, beats in the oscillations appear, as the in-plane angle is slightly tilted from the exact parallel position. The beats are explained from the superposition of oscillations with different periods, corresponding to different effective widths.
