Abstract

We studied the dependence of the maximum tunneling current on external magnetic field for large area Josephson junctions with overlap boundary conditions. We used direct numerical solutions and developed a split Fourier mode method to study the electromagnetic behavior. The steady-state pattern consists of two terms, the first of which satisfies the in-line-like bias current boundary conditions and has zero fluxon content. The second is treated in a mode expansion in the y direction and only two terms are sufficient to reproduce the direct solution of the two-dimensional junction for widths up to 2 p times the Josephson characteristic length. @S1063-651X~96!08007-5#
