We theoretically study the local density of states in superconducting proximity structures where two superconducting terminals are attached to a side surface of a normal-metal wire. Using the quasiclassical Green's function method, the energy spectrum is obtained for both spin-singlet s-wave and spin-triplet p-wave junctions. In both cases, the decay length of the proximity effect at zero temperature is limited by a depairing effect due to inelastic scattering. In addition to the depairing effect, in p-wave junctions the decay length depends sensitively on the transparency at the junction interfaces, which is a unique property of odd-parity superconductors where the anomalous proximity effect occurs.
