Abstract

We show that the equation which describes two- and three-dimensional arrays of small-area Josephson junctions is reduced to the following form, -∇×(∇×φ)-∂2φ/∂t 2-Γ∂φ/∂t = sin φ, where φ is the two- or three-dimensional phase-difference vector, and sin φ is the vector whose components are sine functions of the components of φ, respectively. Based on the above equation we analyze numerically a two-dimensional square network of Josephson junctions, and discuss the vortex motion on the network.
