Query: Finite size effects in metallic superlattice systems   Clean metallic superlattice systems composed of alternating layers of
superconducting and normal materials are considered, particularly aspects of
the proximity effect as it affects the critical temperature. A simple model is
used to address the question of when a finite--sized system theoretically
approximates well a true infinite superlattice. The methods used in the
analysis afford some tests of the approximation used that the pair amplitude of
the Cooper pairs is constant over a superconducting region. We also use these
methods to construct a model of a single superconducting layer which intends to
incorporate a more realistic form of the pair amplitude than a simple constant.
