On the theory of superconducting superstructures

A model structure of the Josephson type formed by periodically alternating layers of superconducting and normal metals (superconducting superlattice) is considered. The influence of phase fluctuations of the order parameter of the superconducting layers on the spectral structure of quasiparticle excitations is investigated. The conditions of applicability of the model under investigation are formulated.
