Abstract
The general solution for ballistic electronic transport through double-barr ier Josephson junctions is derived. We show the existence of a regime of ph ase-coherent transport in which the supercurrent is proportional to the sin gle-barrier transparency and the way in which this coherence is destroyed f or increasing interlayer thickness. The quasiparticle de current at arbitra ry voltage is determined.
