The strength of final-state interaction (FSI) between struck proton and spectator neutron in (2) (H) over right arrow(e,e'p) scattering depends on the alignment of the deuteron. In the framework of the Glauber theory of FSI, which is relevant at GeV energies of the struck proton, we study the resulting FSI effects in the tensor analyzing power in detail and find substantial FSI effects starting at still low missing momentum p(m) greater than or similar to 0.9 fm(-1). At larger p(m) greater than or similar to 1.5 fm(-1), FSI completely dominates both missing momentum distribution and tensor analyzing power. We find that to a large extent FSI masks the sensitivity of the tensor analyzing power to models of the deuteron wave function. For the transversely polarized deuterons the FSI induced forward-backward asymmetry of the missing momentum distribution is shown to have a node at precisely the same value of p(m) as the plane-wave impulse approximation missing momentum distribution. The position of this node is not affected by FSI and can be a tool to distinguish experimentally between different models for the deuteron wave function.
