Fig. 1: Schematics of a planar Josephson junction.
From: Diode effect in the Fraunhofer pattern of disordered planar Josephson junctions
A magnetic field yields a position-dependent phase that induces a diffractive Fraunhofer pattern in the critical current. The cross-product between the current and the magnetic field determines the mirror symmetry plane. a Two-terminal junction and b four-terminal junction.
