  The anomalous proximity effect between a d-wave superconductor and a surface
layer with small electronic mean free path is studied theoretically in the
framework of the Eilenberger equations. The angular and spatial structure of
the pair potential and the quasiclassical propagators in the interface region
is calculated selfconsistently. The variation of the spatially-resolved
quasiparticle density of states from the bulk to the surface is studied. It is
shown that the isotropic gapless superconducting state is induced in the
disordered layer.
