We consider the acoustic propagator A"! ) c in the strip "+(x, z)31"0(z(H, with finite width H'0. The celerity c depends for large "x" only on the variable z and describes the stratification of : it is assumed to be in ΒΈ( ), bounded from below by c '0, such that there exists M'0 with c(x, z)"c (z) i
